Edd Robinson 98d584b63f Use index for SHOW X meta queries
When a meta query does not include a time component then it can be
answered exclusively by the index. This should result in a much faster
query execution that if the TSM engine was engaged.

This commit rewrites the following queries such that they make use
of the index where no time component is present:

  - SHOW MEASUREMENTS
  - SHOW SERIES
  - SHOW TAG KEYS
  - SHOW FIELD KEYS
