Description

There are currently no real checks being performed against connector names and thus a lot of characters are allowed that create issues subsequently when trying to query connector state or delete connectors.
KAFKA-4930 blacklists a few of the obvious culprits but is far from a final solution.

We should come up with a definitive set of rules for connector names that can then be enforced.

Kafka is very restrictive where topic names are concerned, it only allows the following characters: a-zA-Z0-9._-
For Connect we may want to be a bit more forgiving, but probably not too much so, to avoid having to go back and fix things that were missed multiple times.
