BrentOzarULTD#293 sp_BlitzCache - Support for @OutputServerName

This variable now works on sp_BlitzCache! Same limitations as sp_Blitz
when trying to populate an XML field cross server, so query plans return
as NVARCHAR(MAX).

    excluded by default.
  - @IgnoreQueryHashes and @only_query_hashes require a CSV list of hashes
    with no spaces between the hash values.
- - @OutputServerName is not functional yet.
+ - @OutputServerName is functional, but query plans will return as NVARCHAR(MAX)
+   rather than XML, and the summary table will not be stored.
 
 Unknown limitations of this version:
  - May or may not be vulnerable to the wick effect.
