Although we do not support websocket configuration changes, we usually
try to support changes to TLS certificates, etc..
The way websocket is handled (using an http server), the TLS config
was given on startup and updates following a configuration reload
would not be reflected.
Using a tls.Config function that allows passing the tls config
prior to handshake seem to workaround this issue.
I have added a test that demonstrate that the TLS configuration
is really updated after the reload.

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.
Currently, temporary test files and directories are written in lots of
different paths within the OS's temp dir. This makes it hard to know
which files are from nats-server and which are unrelated. This in turn
makes it hard to clean up nats-server test files.
* [fixed] issue with concurrent account fetch when account was incomplete
This happened when a dummy (expired/incomplete) account was created during
a route operation. The dummy was to avoid fetching the account, which would
cause a lock inversion.
When a non route request required the account, we'd download it as it is
set to expired.
A concurrent request would result in ErrAccountResolverSameClaims which
the caller did not handle.
Fix is to remove ErrAccountResolverSameClaims.

If leafnodes from a cluster were to reconnect to a server in
a different cluster, it was possible for that server to send
to the leafnodes some their own subscriptions that could cause
an inproper loop detection error.
There was also a defect that would cause subscriptions over route
for leafnode subscriptions to be registered under the wrong key,
which would lead to those subscriptions not being properly removed
on route disconnect.
Finally, during route disconnect, the leafnodes map was not updated.
This PR fixes that too.

In error conditions or when replacing an existing sub qos1 to qos0,
we were unsubscribing the NATS subscription, but that would not
have been propagated across the cluster.
Also fixed a flapper

We now make sure to sync state of the replicas when a new leader takes over. We also update ack floors regardless of detection on pending list.

When a random port is selected (likely in tests), the banner would
print the port as `0` instead of its real value.

If an update was asssigned but failed at the stream group server we would send back the result which would always delete the stream.
