df27c5b76f Allow gh-ost to modify the server using extra port 
Both Percona and Maria allow MySQL to be configured to listen on an extra port when their thread pool is enable.

* https://www.percona.com/doc/percona-server/5.7/performance/threadpool.html
* https://mariadb.com/kb/en/the-mariadb-library/thread-pool-in-mariadb-51-53/

This is valuable because if the table has a lot of traffic (read or write load), gh-ost can end up starving the thread pool as incomming connections are immediately blocked.

By using gh-ost on the extra port, MySQL locking will still behave the same, but MySQL will keep a dedicated thread for each gh-ost connection.

When doing this, it's important to inspect the extra-max-connections variable. Both Percona and Maria default to 1, so gh-ost may easily exceed with its threads.

An example local run using this

```
$ mysql -S /tmp/mysql_sandbox20393.sock -e "select @@global.port, @@global.extra_port"
+---------------+---------------------+
| @@global.port | @@global.extra_port |

Add a force-table-names command flag 
usage example:
```
gh-ost  ...  --force-table-names=migration_tbl
```

The force-table-names flag will receive a table name and use that name
when creating the _del, _gho, _ghc tables.
For instance for that example above, the tables would be:

_migration_tbl_del
_migration_tbl_gho
_migration_tbl_ghc
