[AtlasDB Proxy & DbKVS] Part 1: Long Identifier Support in Oracle

[jeremyk-91]

Goals (and why):

• Newer versions of Oracle support identifiers of up to 128 characters, and we use this versions. The restriction of identifiers of up to 30 characters, and for prudent reasons table prefixes of 7 characters and overflow table prefixes of 6 characters should no longer apply.
  ==COMMIT_MSG==
  ==COMMIT_MSG==

Implementation Description (bullets):

• Configurably allow explicit support for long identifiers.
• But only permit the use of long identifiers where table mapping is not used: we don't plan on using this in atlasdb proxy.

Testing (What was existing testing like? What have you done to improve it?):

• Added unit tests relating to table prefixes and explicit enabling or not of long prefix names.

Concerns (what feedback would you like?):

• Is the restriction that table mapping doesn't work nicely with this reasonable?

Where should we start reviewing?: OracleDdlConfig

Priority (whenever / two weeks / yesterday): this week please!
