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.

Changed the introduced new option and added a new one. The idea
is to be able to differentiate between never connected and reconnected
event. The never connected situation will be logged at first attempt
and every hour (by default, configurable).
However, once connected and if trying to reconnect, will report every
attempts by default, but this is configurable too.
These two options are supported for config reload.

This is a continuation of #1000. Added a configuration to specify
the number of attempts at which the repeated error is reported.
The algo is now to print only the 1st attempt and when current
attempt % <this config param> == 0.

----------------------------------------------------------------
Backward-incompatibility note:
Varz used to embed *Info and *Options which are other server objects.
However, Info is a struct that servers used to send protocols to other
servers or clients and its content must contain json tags since we
need to marshal those to be sent over. The problem is that it made
those fields now accessible to users calling Varz() and also visible
to the http /varz output. Some fields in Info were introduced in the
2.0 branch that clashed with json tag in Options, which made cluster{}
for instance disappear in the /varz output - because a Cluster string
in Info has the same json tag, and Cluster in Info is empty in some
cases.
For users that embed NATS and were using Server.Varz() directly,
without the use of the monitoring endpoint, they were then given
access (which was not the intent) to server internals (Info and Options).
Fields that were in Info or Options or directly in Varz that did not
clash with each other could be referenced directly, for instace, this
is you could access the server ID:
v, _ := s.Varz(nil)
fmt.Println(v.ID)
Another way would be:
fmt.Println(v.Info.ID)
Same goes for fields that were brought from embedding the Options:
fmt.Println(v.MaxConn)
or
fmt.Println(v.Options.MaxConn)
We have decided to explicitly define fields in Varz, which means
that if you previously accessed fields through v.Info or v.Options,
you will have to update your code to use the corresponding field
directly: v.ID or v.MaxConn for instance.
So fields were also duplicated between Info/Options and Varz itself
so depending on which one your application was accessing, you may
have to update your code.
---------------------------------------------------------------
Other issues that have been fixed is races that were introduced
by the fact that the creation of a Varz object (pointing to
some server data) was done under server lock, but marshaling not
being done under that lock caused races.
The fact that object returned to user through Server.Varz() also
had references to server internal objects had to be fixed by
returning deep copy of those internal objects.

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:

Changed account lookup and validation failures to be more understandable by users.
Changed limits to be -1 for unlimited to match jwt pkg.

Longer term this code should be reworked such that options only hold config data, not real structs, etc.
