MDL-72283 caching: internationalize redis session handler error
The 'unable to obtain session lock'-exception raised by the Redis
session handler is hardcoded in English and not all that useful
to the end user.
This change adds the error message to the lang/error.php and gives
the user further hints why the error might have occured and how it
could be fixed.
