Open XDMoD 10.0.0 Release Candidate 2

Fix schema version history (#1608)

* Fixing datetime columns default values

This commit adds a default value of `CURRENT_TIMESTAMP` to
schema_version_history's `action_datetime` column and removes the
associated value from `./etl_data.d/**/schema-version-history.json`
files.

This was found to be a problem in CentOS8 builds.

* Adding sql to cover the upgrade path.

* Removing schema_version_history table

- Removed all references to schema_version_history as it is not currently being
used.
- Added a sql script that removes all schema_version_history tables if they are
present.

* Missed one

* Removing all db related contents

Since the db table associated with this class / functions / variables is no
longer present, they are no longer necessary.

* Replacing mod_logger data sql

* Woops needed that

* Apply suggestions from code review

Reverting unintended spacing changes.
