Share tags

[RoccoSmit]

As per #3103, #3985 and #4178 users are currently not able to share tag across workspaces.

This PR is to allow for workspace and public tags to be shared.

Design decision:

• I tried to keep with the current design of using the ListMemos endpoint and setting the data that is needed via the request.View flag similar to what is done with memos vs metadata. I could not piggyback off the metadata flow as the metadata numbers would include other user's memos as well
• I started going down the path of creating a generic filter structure and consumer that would allow for building filters that have multiple checks, but it got very involved so I went for the simpler adding of the ShareTags property on the filter object and adding extra SQL to go along with it.
• Users can rename and edit other user's tags. This will only take effect on memos that are marked as workspace or public
• I didnt want the PR to get too big so I did not add other languages for the share tags setting. I can do that separately if the PR gets approved.

Experience:

in the below examples there are 2 users (User-1 and User-2). They both have 1 private, workspace and public memo with an identifying tag name in each. each user also has a workspace level link, todo and code memo.
