Websocket support can be enabled with a new websocket
configuration block:
```
websocket {
# Specify a host and port to listen for websocket connections
# listen: "host:port"
# It can also be configured with individual parameters,
# namely host and port.
# host: "hostname"
# port: 4443
# This will optionally specify what host:port for websocket
# connections to be advertised in the cluster
# advertise: "host:port"
# TLS configuration is required
tls {
cert_file: "/path/to/cert.pem"
key_file: "/path/to/key.pem"
}
# If same_origin is true, then the Origin header of the
# client request must match the request's Host.
# same_origin: true
# This list specifies the only accepted values for
# the client's request Origin header. The scheme,
# host and port must match. By convention, the
# absence of port for an http:// scheme will be 80,
# and for https:// will be 443.
# allowed_origins [
# "http://www.example.com"
# "https://www.other-example.com"
# ]
# This enables support for compressed websocket frames
# in the server. For compression to be used, both server
# and client have to support it.
# compression: true
# This is the total time allowed for the server to
# read the client request and write the response back
# to the client. This include the time needed for the
# TLS handshake.
# handshake_timeout: "2s"
}

We now share more information about the responder and the requestor. The requestor information by default is not shared, but can be when declaring the import.
Also fixed bug for error handling on old request style requests that would always result on a 408 response.

This contains a rewrite to the services layer for exporting and importing. The code this merges to already had a first significant rewrite that moved from special interest processing to plain subscriptions.
This code changes the prior version's dealing with reverse mapping which was based mostly on thresholds and manual pruning, with some sporadic timer usage. This version uses the jetstream branch's code that understands interest and failed deliveries. So this code is much more tuned to reacting to interest changes. It also removes thresholds and goes only by interest changes or expirations based around a new service export property, response thresholds. This allows a service provider to provide semantics on how long a response should take at a maximum.
This commit also introduces formal support for service export streamed and chunked response types send an empty message to signify EOF.
This commit also includes additions to the service latency tracking such that errors are now sent, not only successful interactions. We have added a Status field and an optional Error fields to ServiceLatency.
We support the following Status codes, these are directly from HTTP.
400 Bad Request (request did not have a reply subject)
408 Request Timeout (when system detects request interest went away, old request style to make dependable)..
503 Service Unavailable (no service responders running)
504 Service Timeout (The new response threshold expired)

This is the first checkin for JetStream. Has some rudimentary basics working.
TODO
1. Push vs pull mode for observables. (work queues)
2. Disk/File store, memory only for now.
3. clustering code - design shaping up well.
4. Finalize account import semantics.
5. Lots of other little things.

This will allow a leafnode remote connection to prevent unwanted
messages to be received, or prevent local messages to be sent
to the remote server.
Configuration will be something like:
```
leafnodes {
remotes: [
{
url: "nats://localhost:6222"
deny_imports: ["foo.*", "bar"]
deny_exports: ["baz.*", "bat"]
}
]
}
```

This allows a node that creates a remote LeafNode connection to
act as it was the hub (of the hub and spoke topology). This is
related to subscription interest propagation. Normally, a spoke
(the one creating the remote LN connection) will forward only
its local subscriptions and when receiving subscription interest
would not try to forward to local cluster and/or gateways.
If a remote has the Hub boolean set to true, even though the
node is the one creating the remote LN connection, it will behave
as if it was accepting that connection.

If resolver is specified separately, it takes precedence.
nsc push automatically adds /accounts. That's why its added here too.
Operator jwt reload is not supported and is not taken into account.
On startup the AccountResolver url is checked and exits if it can't be
reached.

A new config section allows to specify specific TLS parameters for
the account resolver:

Allow auto-rotation of log files when the size is greater than
configured limit.
The backup files have the same name than the original log file
name with the following suffix:
<log name>.yyyy.mm.dd.hh.mm.ss.micros
where:
- yyyy is the year
- mm is the month
- dd is the day
- hh is the hour
- mm is the minute
- ss is the second
- micros is the number of microseconds (to help avoid duplicates)

Added a way to specify which account an accepted leafnode connection
should be bound to when using simple auth (user/password).
Singleton:
```
leafnodes {
port: ...
authorization {
user: leaf
password: secret
account: TheAccount
}
}
```
With above configuration, if a soliciting server creates a LN connection
with url: `nats://leaf:secret@host:port`, then the accepting server
will bind the leafnode connection to the account "TheAccount". This account
need to exist otherwise the connection will be rejected.
Multi:
```
leafnodes {
port: ...
authorization {
users = [
{user: leaf1, password: secret, account: account1}
{user: leaf2, password: secret, account: account2}
]
}
}
```
With the above, if a server connects using `leaf1:secret@host:port`, then
the accepting server will bind the connection to account `account1`.
If user/password (either singleton or multi) is defined, then the connecting
server MUST provide the proper credentials otherwise the connection will
be rejected.
If no user/password info is provided, it is still possible to provide the
account the connection should be associated with:
```
leafnodes {
port: ...
authorization {
account: TheAccount
}
}
```
With the above, a connection without credentials will be bound to the
account "TheAccount".
If credentials are used (jwt, nkey or other), then the server will attempt
to authenticate and if successful associate to the account for that specific
user. If the user authentication fails (wrong password, no such user, etc..)
the connection will be also rejected.
