We will only send if all peers in our group are >= 2.7.1 and we will check for updates.
When a consumer follower takes over it will notify all pending requests that those requests are invalid now.

This should help with GC pressure, however, it may have an effect
on performance (based on some benchmark). Calling sync.Pool.Get/Put
too often has a performance impact...

This allows stream placement to overflow to adjacent clusters.
We also do more balanced placement based on resources (store or mem). We can continue to expand this as well.
We also introduce an account requirement that stream configs contain a MaxBytes value.
We now track account limits and server limits more distinctly, and do not reserver server resources based on account limits themselves.

ClientID has been added to various monitoring objects. Also, added
the ability to filter connections on `client_id`.
On auth violation, the proper code was not invoked, which meant
that no disconnect event (with auth reason) would be published.
Resolves#2270

This is the reverse of the early work to have LNs extend a non-JS cluster.
Also have mixed mode tests as well.

* [fixed] jetstream unique server name requirement across domains
including domain in server info
adding check for cluster name in duplicate leaf node connection check
This does not address non unique domains in the same domain, say within
super cluster.

When processing service imports we would swap out the accounts during processing.
With the addition of internal subscriptions and internal clients publishing in JetStream we had an issue with the wrong account being used.
This was specific to delyaed pull subscribers trying to unsubscribe due to max of 1 while other JetStream API calls were running concurrently.
* [adding] kind and client_type to client info. specifically account connect/disconnect events
Kind is Client/Leafnode but can take the value of Router/Gateway/JetStream/Account/System in the future.
When kind is Client, then client_type is set to mqtt/websocket/nats
This fixes#2291

On export/import a header was inserted which broke parsing of the
message.

This is generally useful but will also help with cli actions since we know from first response how many total responses are expected.

1. When in mixed mode and only running the global account we now will check the account for JS.
2. Added code to decrease the cluster set size if we guessed wrong in mixed mode setup.

Took the approach of storing struct instead of pointer. Of course,
when changing the offline bool from false to true, it means that
we need to call Store again (with same key).
This is based on the assumption that those Load/Store are not too
frequent. Otherwise, we may need to use locking (and keep *nodeInfo)

This also applies to times that end up in that json.
Where applicable moved time.Now() to where it is used.
Moved calls to .UTC() to where time is created it that time is converted
later anyway.

This allows metacontrollers to span superclusters. Also includes placement directives for streams. By default they select the request origin cluster.
