Add in proper support for stream updates in clustered mode.
Don't send API updates without subjects, caused GW parser errors.
Stream internal loops use their own clients now.

Only check limit for CLIENT connection types, however, the check
is done for CLIENT in all conditions, not only in the case of a
split buffer as it was the case so far.

Connections normally suppress sending PINGs if there was some
activity. We now force GATEWAY connections to send PINGs at the
configured interval or 15 seconds, whichever is the smallest.

When creating shadow subscriptions for import streams, we were
not invoking code for gateway subscription accounting, which means
that when the account (for leafnodes) was switched to interest
only, those shadow subscriptions were not sent.

The default TLS timeout has been bumped to 2 seconds.
The default Auth timeout is now 2 seconds, but if TLS config
is present, it is equal to TLS timeout (possibly default value) + 1s.

Leafnodes that formed clusters were partially supported. This adds proper support for origin cluster, subscription suppression and data message no echo for the origin cluster.

The grace period used to be hardcoded at 10 seconds.
This option allows the user to configure the amount of time the
server will wait before initiating the closing of client connections.
Note that the grace period needs to be strictly lower than the overall
lame_duck_duration. The server deducts the grace period from that
overall duration and spreads the closing of connections during
that time.
For instance, if there are 1000 connections and the lame duck
duration is set to 30 seconds and grace period to 10, then
the server will use 30-10 = 20 seconds to spread the closing
of those 1000 connections, so say roughly 50 clients per second.
Resolves#1459.
