[os_must_gather] Make SOS_DECOMPRESS configurable

Expose SOS_DECOMPRESS as `cifmw_os_must_gather_sos_decompress` with a
default of 1 so that SOS reports from both OCP and EDPM nodes are
decompressed after collection, making them directly readable without
extra steps. This keep the original behavior and adapts cifmw to the
recent changes introduced to openstack-must-gather.

 * `cifmw_os_must_gather_namespaces`: (List) List of namespaces required by the gather task in case of failure
 * `cifmw_os_must_gather_additional_namespaces`: (String) List of comma separated additional namespaces. Defaults to `kuttl,openshift-storage,sushy-emulator`
 * `cifmw_os_must_gather_volume_percentage`: (int) Specify maximum percentage of must-gather pod's allocated volume that can be used. If this limit is exceeded, must-gather will stop gathering, but still copy gathered data. Defaults to `80`
+* `cifmw_os_must_gather_sos_decompress`: (int) Controls whether SOS reports collected from both OCP and EDPM nodes are decompressed after gathering. Set to `1` to decompress (default), or `0` to keep them compressed. Decompressing makes the reports directly readable (useful for CI purposes) but increases usage. Defaults to `1`
 * `cifmw_os_must_gather_omc`: (bool) Enables the full gathering method. When set to false, a lightweight mode is used; when true, it performs a comprehensive data collection, which is more resource-intensive. Defaults to `false`
