Tagging validation issues

Met with Ryan M and Chris V to discuss a path forward for dealing with troublesome data submitted to and currently stored in the Tagging Service.

Tags are currently normalized to lowercase
Should we normalize spaces?
Should we disallow or remove commas?
Should we validate only new tags?
- There is no way for the tagging service to know that a tag is already in use elsewhere
How many tags are in the system that meet our definition of malformed?
Should we start by adding validation?
- We could implement a check that only tracks metrics when an added tag fails validation
  - This can be added to awsubs to see how many subscribers we would fail to add

Chris will take some additional time to think through the options.
