Bug Description

Manila tempest plugin is facing issues due to insufficient user credentials after skipping some tests. The Manila test class is raising a skipException during the resource_setup method and the credentials are not being release by the setUpClass.

setUpClass (manila_tempest_tests.tests.api.admin.test_migration.MigrationCancelNFSTest) ... SKIPPED: ('Share migration tests are disabled.',)
setUpClass (manila_tempest_tests.tests.api.admin.test_migration.MigrationOfShareWithSnapshotNFSTest) [0.000000s] ... FAILED

'Details: Insufficient number of users provided. MigrationCancelNFSTest have allocated all the credentials for this allocation request'

The fix seems to be capturing the exception by isn't calling the tearDownClass to cleanup() the allocated resources.

    Call tearDownClass when handling skip exception on setUpClass

    In setUpClass, the workaround to handle skip exception issue is
    not releasing allocated resources when a skip exception is raised
    on resource_setup.
