Users and NKey users will now have the option to specify a list
of allowed connection types.
This will allow for instance a certain user to be allowed to
connect as a standard NATS client, but not as Websocket, or
vice-versa.
This also fixes the websocket auth override. Indeed, with
the original behavior, the websocket users would have been bound
to $G, which would not work when there are accounts defined, since
when that is the case, no app can connect/bind to $G account.

When a leafnode would connect with credentials that had permissions the spoke did not have a way of knowing what those were.
This could lead to being disconnected when sending subscriptions or messages to the hub which were not allowed.

We added authentication override block for websocket configuration
in PR #1463 and #1465 which somehow introduced a drop in perf as
reported by the bench tests.
This PR refactors a bit to restore the performance numbers.
This change also fixes the override behavior for websocket auth:
- If websocket's NoAuthUser is configured, the websocket's auth
block MUST define Users, and the user be present.
- If there is any override (username/pwd,token,etc..) then the
whole block config will be used when authenticating a websocket
client, which means that if websocket NoAuthUser is empty we
are not falling back to the regular client's NoAuthUser config.
- TLSMap always override the regular client's config. That is,
whatever TLSMap value specified in the websocket's tls{} block
will be used.
The TLSMap configuration was not used for LeafNodes. The behavior
now will be:
- If LeafNode's auth block contains users and TLSMap is true,
the user is looked up based on the cert's info. If not found,
authentication will fail. If found, it will be authenticated
and bound to associated account.
- If no user is specified in LeafNode's auth block and TLSMap
is true, then the cert's info will be used against the global
users map.

Websocket can now override
- Username/password
- Token
- Users
- NKeys
- no_auth_user
- auth_timeout
For TLS, support for verify and verify_and_map. We used to set
tls config's ClientAuth to NoClientCert. It will now depend
if the config requires client certificate verification, which
is needed if TLSMap is enabled.

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.

Currently when using TLS based authentication, any domain components
that could be present in the cert will be omitted since Go's
ToRDNSequence is not including them:
202c43b2ad/src/crypto/x509/pkix/pkix.go (L226-L245)
This commit adds support to include the domain components in case
present, also roughly following the order suggested at:

This configuration allows to refer to a configured user to be used when
the connection provides no credentials.

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.

* Added support for account signing keys. When account signing keys change
the validity of the client JWT and token imports need to be checked as well
as it is possible for the signing key used to sign the user or import
token to have been removed from the source account.
What is not completed:
1. TLS
2. config to bind local account.
3. Info updates for solicitor to track topology changes like a client.
4. CONNECT sent after INFO for nonce authroization.
5. Authorization
6. Services and Streams tests.
7. config file parsing.

Similar as with clients, this makes it possible to
use the subject from a TLS certificate to validate
the permissions from a cluster member.
Currently only a single configured user is supported:

key_file = "./configs/certs/tlsauth/server-key.pem"
ca_file = "./configs/certs/tlsauth/ca.pem"
verify_and_map = true
timeout = 2
}
permissions {
publish {
allow = ["public.>"]

subscribe {
allow = ["public.>"]
}

authorization {
user = "CN=localhost,OU=NATS.io Operators"
