Parameter for action database

Issue #2927799 on drupal.org by drupatz.

Scenario:

• I would like to download database dumps for eg. 25 domains. For obvious (eg. performance) reasons, sometimes i only need 'neccessary' tables for eg. importing the database in another step. So in this case, i eg. don't need the cache tables.

• On the other side, for maybe bug-search purposes, i would like to download only certain tables from these 25 databases to compare them later on.

So it would be very helpful, to have at least 1 parameter with options for this action:
Example:
1. Radio buttons: all, exclude_tables and only_tables.
2. Textarea to put in the table names.

This input should be easily able to get added to the build of the mysql string.

What's your opinion? Have a better solution or am i missing something?
I'd look forward to write a patch and put it in here, if you don't mind.
