[FEATURE] Add support for excluding tables

[bplunkett-stripe]

Describe the feature
Provide a thorough description of the feature. If possible, include examples of the feature and its behavior. For example, if it's a new command flag, provide examples of using the command flag and expected outputs.
Just like schemas, some tables may need to be excluded from the migration plan. Because exclusion will probably get pretty complex, we may want to create some predefined grammar to avoid parameter explosion:

--exclude 'type=[schema|table] name="regex"'

*Motivation
Describe why you want this feature. This is important for assessing the priority of the feature and if alternative solutions exist.
