Support wildcard table structure-only dumps

[bomoko]

Drush's sql-sync has the ability to exclude tables based on patterns.

A new feature that could, for example, all tables with the structure cache_* is required for lagoon-sync to have parity here.

This feature has been requested by a customer, basically the same functionality as the drush command, so structure only on a table pattern.

@seanhamlin so we are talking about replicating the structure-tables-list that drush supports? essentially returns the structure, but no data?

Do we want to expand on this issue and include a --no-data option as well?https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#option_mysqldump_no-data

[seanhamlin]

Correct, an example use case is to do structure only (so skip the data) for tables that match

• cache
• cache_%
• watchdog
