Allow silencing dbcritic issues using globs or regexes

[maartenberg]

This is a copy of a previously-internal issue.

dbcritic's issue silencing mechanism currently only allows silencing issues by specifying the exact table names.
This is a problem if there are many tables where the issue needs to be silenced (and/or these tables are dynamically created, so the name isn't known in advance).

It would be nice if we could specify the following in .dbcriticrc:

silence primary_key timeseries_agg_*

Or we could even generalize it to using regexes, if calling PCRE using the FFI is sufficiently easy (probably is):

silence primary_key /^timeseries_agg_/
