52c724a83c Updates based on comments
- Solve RS+ with wildcards
- Solve issue with messages not send to remote gateways queue subs
  if there was a qsub on local server.
- Made rcache a perAccountCache since it is now used by routes and
  gateways
- Order outbound gateways only on RTT updates
- Print a server's gateway name on startup
- Augment/add some tests
- Update TLS handling: when connecting, use hostname for ServerName
  if url is not IP, otherwise use a hostname that we saved when
  parsing/adding URLs for the remote gateway.
- Send big buffer in chunks if needed.
- Add caching for qsubs match

eb17950971 Introduce some delay before closing clients in LameDuck mode.
This will allow to signal multiple servers at once to go in
that mode and not have their client reconnect to one of the
servers in the group.

c173d55e2e Update based on comments
Start the lame duck mode in a go routine in the signal handler
because I think we want to be able to shutdown the server while
in that mode.

Kept the closing as a loop in the lameDuckMode() function (did
not use a timer).

0067c3bb04 Added support for lame duck mode
When receiving SIGUSR2 signal (or -sl ldm) the server stops
accepting new clients, closes routes connections and spread the
closing of client connections based on a config lame duck duration
(default is 30sec). This will help preventing a storm of client
reconnect when a server needs to be shutdown.

c35607cd95 [ADD] internal option to write a ports file --ports_file_dir
The added option writes a file in the specified directory called <exename>_<pid>.ports which
contains a JSON representation of ports that the gnatsd has opened.

This change is intended to facilitate testing by having ports be specified with a -1, so
they are auto assigned and allow tests to locate and connect to the launched gnatsd(s).

ac42bb0bb9 Remove route connection from temp map
When a route connection is created, the server will keep track
of the client structure in a special map until the route protocol
completes. This is meant so that if the server is shutdown before
the route is registered in routes map, the server can kick out
the connection's readLoop.

The route connection was correctly removed on success, but was
not for route connections that were not registered and dropped.
This was not causing any issue, but for correctness, doing the
removal now when server removes a route connection.
