Stephen Finucane 5a97e855f5 db: Replace implicit conversion of SELECT into FROM 
Resolve the following warnings issued in recent versions of SQLAlchemy:

  SADeprecationWarning: Implicit coercion of SELECT and textual SELECT
  constructs into FROM clauses is deprecated; please call .subquery() on
  any Core select or ORM Query object in order to produce a subquery
  object.

The resolution is simple: instead of using 'FromClause.alias', use
'Query.subquery'. A warning filter is included to prevent us
reintroducing this issue in the future. It can be dropped once we start
using SQLAlchemy 2.0 where this behavior will be removed.

This change requires bumping SQLAlchemy to 1.4.0, which is the first
version to introduce the selectable '.subquery()' method. We must also
bump oslo.db to 8.6.0, which is the first version to support SQLAlchemy
1.4.x. The alternative would be to introduce a switch based on
SQLAlchemy versions, but that's tech debt that'll have to be cleaned up.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
