Add tests for package migration/renaming

[m1kola]

Description of the change:

Tests upgrades from one package to another within the same subscription. This is useful when renaming operator package.

No new features introduced: this is currently supported by OLM, but there are no tests for this.

Motivation for the change:

I'm currently working on migrating from one package name to another one and want to make sure this is supported by tests. From my experience this need arises from time to time: companies rename/rebrand their products and want pack names to match.

Architectural changes:

None

Testing remarks:

Adds tests
