[SPARK-15789][SQL] Allow reserved keywords in most places
## What changes were proposed in this pull request?
The parser currently does not allow the use of some SQL keywords as table
or field names. This PR adds supports for all keywords as identifier. The
exception to this are join aliases, in this case most names are allowed except
for: ```anti, full, inner, left, semi, right, natural, union, intersect,
except, database, on, join, cross, select, from, where, having, from, to,
table, with, not```.
## How was this patch tested?
I have added/move/renamed test in the catalyst `*ParserSuite`s.
