General test flow:
- server is started with file_key_management plugin and keys, otherwise default options;
- a few InnoDB tables are created;
- several threads are running DML on these tables;
- one thread is running ALTER TABLE with different values of ENCRYPTED and ENCRYPTION_KEY_ID, and also toggles innodb_encryption_threads and innodb_encrypt_tables glboal variables;
- the server gets intentionally crashed and restarted periodically.

MDEV-8817: Failing assertion: new_state->key_version != ENCRYPTION_KEY_VERSION_INVALIDAnalysis: Problem sees to be the fact that we allow creating or altering
table to use encryption_key_id that does not exists in case where
original table is not encrypted currently. Secondly we should not
do key rotation to tables that are not encrypted or tablespaces
that can't be found from tablespace cache.
Fix: Do not allow creating unencrypted table with nondefault encryption key
and do not rotate tablespaces that are not encrypted (FIL_SPACE_ENCRYPTION_OFF)
or can't be found from tablespace cache.
