This is the first checkin for JetStream. Has some rudimentary basics working.
TODO
1. Push vs pull mode for observables. (work queues)
2. Disk/File store, memory only for now.
3. clustering code - design shaping up well.
4. Finalize account import semantics.
5. Lots of other little things.

As a consequence of this change, certain unit tests had to actually
start the server and move to a memory resolver to keep the test simpler.

Fixes#1372 by updating s.sys.account pointer.
This issue also showed that accounts are unnecessarily reloaded.
This happened because account imports were not copied and thus,
deepEqual detected a difference were none was.
This was addressed by making the copy less shallow.
Furthermore did deepEqual detects a difference when it compared
slices that were appended to while processing a map.
This was fixed by sorting before comparison.
Noticed that Account.clients stored an unnecessary pointer.
Removed duplicated code in systemAccount.

Currently when using TLS based authentication, any domain components
that could be present in the cert will be omitted since Go's
ToRDNSequence is not including them:
202c43b2ad/src/crypto/x509/pkix/pkix.go (L226-L245)
This commit adds support to include the domain components in case
present, also roughly following the order suggested at:

If the connection is marked as closed while sending the INFO, the
connection would not be removed from the internal map, which would
cause it to be shown in the monitoring list of opened connections.

This configuration allows to refer to a configured user to be used when
the connection provides no credentials.

If a node in the cluster goes away, an async INFO is sent to
inbound gateway connections so they get a chance to update their
list of remote gateway URLs. Same happens when a node is added
to the cluster.

This gives the close reason directly in the log without having to
get that information from the monitoring endpoint. Here is an
example of a route closed due to the remote side not replying to
PINGs:
```
[INF] 127.0.0.1:53839 - rid:2 - Router connection closed: Stale Connection
```
Without this change, the log statement would have been:
```
[INF] 127.0.0.1:53839 - rid:2 - Router connection closed
```

Make use of some existing helpers and add checkFor in some places
since accounting updates may not be instantaneous.
