This is the first pass at introducing exported services to the system account for generally debugging of blackbox systems.
The first service reports number of subscribers for a given subject. The payload of the request is the subject, and optional queue group, and can contain wildcards.

What is not completed:
1. TLS
2. config to bind local account.
3. Info updates for solicitor to track topology changes like a client.
4. CONNECT sent after INFO for nonce authroization.
5. Authorization
6. Services and Streams tests.
7. config file parsing.

Allow deny clauses for subscriptions to still allow wildcard subscriptions but do not deliver the messages themselves.

This would manifest for instance when server tries to send messages
to queue subscribers and a subscription is unsubsribed at the same
time.

This is similar to #561 where `*` and `>` characters appear in tokens
as literals, not wilcards.
Both Insert() and Remove() were checking that the first character
was `*` or `>` and consider it a wildcard node. This is wrong. Any
token that is more than 1 character long must be treated as a literal.
Only for token of size one should we check if the character is `*`
or `>`.
Added a test case for Insert and Remove with subject like `foo.*-`
or `foo.>-`.
The issue was that a subject such as `foo.bar,*,>` would be
inserted to the cache as is, but when trying to remove from the
cache, calling matchLiteral() with the above subject in the cache
against the same subject would return false. This is because
matchLiteral would treat those characters as wildcards token.
Note that the sublist itself splits subjects on the `.` separator
and seem not bothered by such subject (would have `foo` and `bar,*,>`
tokens). Also, note that IsValidSubject() and IsValidLiteralSubject()
properly checked that the characters `*` and `>` are treated
as wildcards only if they are tokens on their own.
