Good afternoon!

I think it would be better to add a macro to the MySQL plugin in which you can specify a list of databases that do not need to be detected.

For example, this is very conveniently implemented in the MongoDB plugin:

{$MONGODB.LLD.FILTER.DB.NOT_MATCHES} (admin|config|local)

At the moment, a similar regular expression does not work in the MySQL plugin.
I had to set a separate filter for each database in "mysql.db.discovery", but this is not very convenient.

Maybe there is some other way to specify multiple databases in a filter that I don't know about yet.
