Previously an NullPointerException would be thrown if the Pulse was a
bar graph and the resultset contained a nil value for the x or y
axis. This commit just omits those rows so that it doesn't fail and
renders the data it does have.

Fixes #8260

 Add a JoinQuery to `metabase.query-processor.interface`

Just adds a `:user` keypair with the current user information.

This will allow expressions in a join clause, rather than just a table name.

Fix issues with remappings and FKs with nested queries

Ensure that the new nested query FK tests don't run on drivers that
don't support both nested queries and FKs. Also needed to fixup
integer data types for Oracle and a nested order by issue for SQLServer

Mostly this change involves resolving the nested query, then using
that resolved nested query along with the top level breakout clause to
figure out if we need to add more fields to be projected from that
inner query.

The code previously was resolving that nested query but wasn't
resolving the breakouts after and reconciling that fields list. This
also adds some tests for these nested FK scenarios.
