Our existing remappings code didn't work when an MBQL fields clause is
present. Typically that fields clause is populated by the
`add-implicit` middleware, but that doesn't happens with the user
included fields.

Add missing Redshift driver password field

Dataset exports should check for nested queries

The redshift connection configuration details got messed up in the
refactor. Instead of the password field a second port field got
included. The password field was put back in but the second port field
needed to get removed.

Ensure base type in result metadata

When POSTing to the `/dataset` endoint, there was code that if the
database was our fake database id (used for nested queries) but that
same check wasn't present for the dataset exports. This commit adds
that check and a test that validates it.

Fixes #8256

Fix bug with MySQL date tz conversion for native queries

The issue was around our usage of `du/format-date` with a built-in
date format (`:date-hour-minute-second-ms`). Those Joda Time date
formatters don't default to the system timezone, which the code
assumed. Instead it defaults to UTC. We have code in the MySQL driver
that works around a MySQL driver bug by converting the date to a
string and then using the MySQL `convert_tz()` function. That code was
converting the date from the system timezone to the report timezone,
rather than UTC, which is what the Joda Time date formatter was
returning.

Fixes #8262

Pulse graphs should skip nil value rows

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
