The issue really was that the test was sharing remote options. The
way options are used is not ideal since we reference the user provided
options (but it is relied upon now in many tests and possibly users
setups). The other side of the issue was that when no local account
is specified in a "remote" specification, we set it to the global
account, but that was done when creating the leafnode object (when
soliciting), which in the case of the test could race with the
second server doing the validation.
In this PR we move the setting to global account during the validation,
but also fixed the tests to not share the remote options configuration
slice between the two servers.

Allows (exposes) the existing cluster filtering option of account level
subject mapping, thereby allowing you to define different mapping
destination per cluster (e.g. to insert the cluster name as a subject
token).
Example:
```
mappings {
"foo":[
{destination:"foo-east", cluster: "east", weight:100},
{destination:"foo-west", cluster: "west", weight:100},
]
}
```
1. When catching up do not try forever and if needed reset cluster state.
2. In checking if a stream is healthy check for node drift.
3. When restarting a stream make sure the current node is stopped.

This is similar to PR #4115 but for LeafNodes.
Compression mode can be set on both side (the accept and in remotes).
```
leafnodes {
port: 7422
compression: s2_best
remotes [
{
url: "nats://host2:74222"
compression: s2_better
}
]
}
```
Possible modes are similar than for routes (described in PR #4115),
except that when not defined we default to `s2_auto`.

When the first block was truncated and missing any index info we would
not properly rebuild the state.

### Changes proposed in this pull request:
There is currently a blanket requirement that subject transforms
destinations MUST use ALL of the partial wildcards defined in the source
of the transform. This is because the subject transformed defined for
imports must be 'reversible' and therefore the destination transform
must use all of the partial wildcard tokens defined in the source of the
transform.
This reversing of a transform is only used for transforms used by
imports, where in any case it doesn't make sense to use any transform
other than Wildcard.
This PR:
- relaxes this requirement to only apply when the transform is used by
an import, adding the ability to drop a wildcard token in transforms
other than as part of an import.
- Improves transform reverse to support both legacy style wildcards $X
and the new transform function {{Wildcard(X)}}- Improves reversible
transform checking to only allow the use of wildcards in the
destination.

When using the nats account resolver and a JWT is not found, the client could
often get an i/o timeout error due to not receiving a timely response
before the account resolver fetch request times out. Now instead
of waiting for the fetch request to timeout, a resolver without JWTs
will notify as well that it could not find a matching JWT, waiting for a
response from all active servers.
Also included in this PR is some cleanup to the logs emitted by the
resolver.
