I'm adding this to the SQL tracker issue. It is more low priority
but we should think about doing it before merging because it is
fairly easy:
Exceptions have many constructors that take a string pattern and
arguments. These kinds of things have mostly been removed in core
because we prefer explicitly building the message at the call site
for clarity. We should probably remove these constructors because
it is easy and another way that we can be more like core quickly.

This is a hack to remove a dependency cycle I added in elastic/x-pack-elasticsearch#2109. I think
it'd be cleaner to remove the cycle by making sql its own plugin that
doesn't depend on the rest of x-pack-elasticsearch but is still
included within x-pack-elasticsearch. But that is a broader change.

To avoid leaking client information across the entire code-base, client
settings like TimeZone or pagination are stored in
SqlSession>SqlSettings which are available as a ThreadLocal (during
analysis) so that components that need them, can pick them up.
Since ES internally uses Joda, the date/time functionality relies on Joda,
whenever possible to match the behavior.
