This is related to PR #2407. Since the 64MB pending size is actually
configurable, we should fail only if max_payload is greater than
the configured max_pending. This is done in validateOptions() which
covers both config file and direct options in embedded cases.
The check in opts.go is reverted to max int32 since at this point
we don't know if/what max_pending will be, so we simply check
that it is not more than a int32.
For the next minor release, we could have another change that
imposes a lower limit to max_payload (regardless if max_pending
is higher).

Issuing a configuration reload for a leafnode that has remotes
defined with remotes having more than 1 url could lead to a failure.
This is because we have introduced shuffling of remote urls but
that was done in the server's options object, which then would
cause the DeepEqual when diff'ing options to fail.
We move the suffling to the private list of urls.
The other issue was that the "old" remote option may not have
had a local account and it was not set to "$G", which could make
the DeepEqual fail.

* [added] pinned_cert option to tls block hex(sha256(spki))
When read form config, the values are automatically lower cased.
The check when seeing the values programmatically requires
lower case to avoid having to alter the map at this point.

If running the server with command lines:
```
nats-server --tlsverify --tlscert "cert.pem" --tlskey "key.pem"
```
the default ciphers would not be set, however, they would using this
equivalent config:
```
tls: {
verify: true

key_file: "key.pem"

This was introduced by PR #2071.
On some tests, options are loaded based on a config file that has
the pid set to "/tm/nats-server/nats-server.pid", however, the
expected option's pid path was set based on tmpRoot. The problem
is that on macOS, that value would be "/var/folders/xxx" which
would not match.
So this PR simply reverts the changes to the expected pid file
name: it simply needs to match was in the test.conf file.

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.
This change does 4 things:
Refactor to only have one function to validate imports.
Have this function support the jwt field account_token_position.
For completeness make this value configurable as well.

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.

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.

Running test suite on a Windows VM, I notice several failures.
Updated the compute of the RTT to be at least 1ns. I think that
this is just an issue with the VM I am running, but that change
will have no impact for normal situations (since setting the rtt
to the very minimum duration (1ns) instead of 0) and will prevent
some tests from failing.
Because of those same timer granularity issues, I had to add some
delays between some actions in order for time.Sub()/Since() to
actually report something more than 0.

Currently, the $SYSTEM subject is used in this repo, but it seems like this
subject name is out of date.
This change updates the code to use $SYS to match the documentation.
This was introduced in PR#930. The first commit had the route's
check if the flushOutbound() returned false, and if so would
locally unlock/lock the connection's lock. Unfortunately, this
was replaced in the second commit (a6aeed3a6b)
to the flushOutbound() function itself.
This causes the function closeConnection() to possibly unlock
the connection while calling flushOutbound(), which if the
connection is closed due to both a tls timeout for instance
and explicitly, it would result in the connection being scheduled
for a reconnect (if explicit gateway connection, possibly route).
Added defensive code in Gateway to register a unique outbound gateway.
Fixed a test that was now failing with newer Go version in which
they fixed url.Parse()
