Remove some old options, now deprecated (December 2024)

[stronk7]

With the new "split runner" (see #111) now in prod, we proceeded to rename and deprecate some old configuration options:

• DBSLAVES => DBREPLICAS
• TESTTORUN => JOBTYPE
• TESTSUITE => PHPUNIT_TESTSUITE
• TAGS => PHPUNIT_FILTER
• TAGS => BEHAT_TAGS
• NAME => BEHAT_NAME
• BEHAT_TOTAL_RUNS => BEHAT_PARALLEL
• BEHAT_NUM_RERUNS => BEHAT_RERUNS

Right now, all them are just deprecated and the new runner does the appropriate conversion when needed.

This is issue is about to, in December 2024, proceed with the removal of all the old options above. All them will stop the execution with an error instead of showing the deprecation warnings.

Also, it may be a good time to remove the master branch from the repository. It contains the previous runner that has been completely replaced by the new one in the main branch.

Ciao :-)
