This is a followup patch to commit edb72cb70cb8abd0acb92f07937715be2816d04a to support related lvm2 test suite tests. A 'global/support_mirrored_mirror_log' bool configuration variable gets introduced allowing the creation of, or conversion to mirrored 'mirror' logs if set. The capability to create these in turn allows the rest of the tests to perform activation of such existing LVs and their conversions to disk/core 'mirror' logs. Display a disclaimer warning if enabled that this is not for regular use. Add definition of the enabled config option to respective test scripts. Related: rhbz1643562
