Currently in tests, we have calls to os.Remove and os.RemoveAll where we
don't check the returned error. This hides useful error messages when
tests fail to run, such as "too many open files".
This change checks for more filesystem related errors and calls t.Fatal
if there is an error.
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.

Added cluster names as required for prep work for clustered JetStream. System can dynamically pick a cluster name and settle on one even in large clusters.

- TestResponsePermissions: ensure subscription for service is
registered by server before sending requests.
- TestReloadDoesNotWipeAccountsWithOperatorMode: wait for subject
propagation.

Some tests consume too much memory when running with -race which
can cause some failures on Travis.
Moreover, those tests may not be meaningful if they are running
slow, which -race causes.

Refactor the way client is initialized. We need to ensure that
clients are not added to the clients map and readLoop started if
the server is in the process of being shutdown otherwise there
is a chance that the server already gathered the list of connections
to close and this one would not be included, leaving a readLoop
running.
Same occurs for routes, with the complexity that the readLoop is
started well before the route connection is added to the server
routes' list. We need a temporary map that contains those connections
to be able to close them on server Shutdown.
Fixed some flapping tests.
Both seed and chained cases are now handled properly when servers
connect quickly and concurrently to one another.
When accepting a route, the server will forward the new route INFO
protocol to its known routes. In turn those routes will connect
to the new server (if not already connected).
A retry for implicit route was introduced to mitigate the issue
with two servers connecting to each other and electing the opposite
connection as the winner, resulting in both connections being dropped.
The server with smaller ID will try once to reconnect.
Some tests were fixed to handle possible extra INFO protocol.
New tests added.
