This update for suse-migration-services fixes the following issues:

- Bump version to 2.1.33:
    * Fix btrfs snapshot services
      Do not perform snapshot operations if the root filesystem is not btrfs based.
    * Fix lsm precheck
      Yet another test that doesn't restrict the scope of its runtime environment.
    * Fixed scope check for cpu_arch and check_ha
    * Update documentation
- Bump version to2.1.32:
    * Fixed dataProvider setup in regionserverclnt.cfg
      In case of Azure the dataProvider information gets a device parameter added.
      This parameter must be added only once or not at all if it is already present.
    * Fixup import of certificates
      Only import if the file exists and is not a directory. We still assume that the file content of
      the pki trust directories matches certificates and not random non certificate files.
    * Fix consistency of regionserverclnt.cfg (bsc#1258710)
- Bump version to 2.1.31:
    * Doc update
      Weave in more updates about the SLE 15 to 16 migration. While we have updated the code to support
      the migration to 16, the doc has been lacking appropriate references.
    * Fix setup of migration target for pre-check (bsc#1258174)
    * Make sure to fallback to scc.suse.com
      Systems that are not providing /etc/SUSEConnect should fallback to
      the default registration server which is https://scc.suse.com
    * Update test data
    * Switch reboot default
    * Be more explicit about kexec example
      Make it more explicit that Xen is only one example where kexec does not work.
    * Update documentation
    * Add wicked2nm-continue-migration to user doc
    * Move default container to official devel project
    * Fixed disk device name passed to azuremetadata
    * Fix SLES SAP migration 12 - 15 in public clouds
    * Fix python compatibility on latest zypper change
    * Manage documentation version
      Make sure documentation version and code version are consistently managed.
