5f15f8a539 Remove not needed call by grouping columnLists 
There is no need to call `applyColumnTypes` more than once for the same
`databaseName` and `tableName`, it is just move the additional
`columnList` to the first call.

dfc8aa28f4 Ignore not available columns when applying column types 
The given `columnLists` may not contain all columns available in the
given table. This patch prevents the code to fail. Before this patch the
code was panicking whenever it was trying to set a value into a `nil`
object, e.g. `columnList.GetColumn('non-existant').Type = SomeType`.

For some reason the application was not completely failing but as a
side-effect any column after the non-existant column would never get its
Type properly set.

Populate the env with dry run status 
Updates the `applyEnvironmentVariables` function to populate whether or
not the current execution context is running as a dry run or not which
can then be used in hooks.

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 |
