Rewrite gora-sql module via JOOQ Library

[Mohamed Infaz <in...@gmail.com>]

Hi All,

I am a GSOC student and my proposal on [1]
<https://issues.apache.org/jira/projects/GORA/issues/GORA-86>
<https://issues.apache.org/jira/projects/GORA/issues/GORA-86> got accepted
and my community bonding period is over. In this period I have submitted
one pull request [2] <https://github.com/apache/gora/pull/245> apart from
the previous two pull requests [3] <https://github.com/apache/gora/pull/238>
and [4]
<https://github.com/apache/gora/commit/cd28146e4b4ad59587f2ad4c2748905954f837d8>
where the last one is in Master branch now.

I have talked to my mentors who are Madhawa & Kevin on how to implement
this. If you have any insights on how I should continue, please let me
know.
