Review implementation of ColumnValuesToMatchRegex

[pmbrull]

Feature
Based on #1311

Describe the task
Two things to check here:

• Regex strategy to follow: @harshach are we talking about python-level regex or aiming towards SQL-supported 'LIKE' syntax? I am assuming the second, but just to confirm.
• We'll need to review how we want to create tests based on metrics with specific parameters requirements that can change from col to col.

@pmbrull lets use SQL Like and second thing is email regex that we should see if we can pass down to sql instead of doing in python
