inspect: remove redundant join conditions 
The TABLE_SCHEMA and TABLE_NAME are already guaranteed to have the same value in COLUMNS and UNIQUES because of the WHEREs in each query. Dropping it from the ON clause makes it complete much faster.

On (at least) MySQL 5.6 installs with thousands of tables, this query completes in a few seconds without the additional join conditions, but takes more than a minute with it.

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 |
