[feature] User muting (#2960)
* User muting

* Address review feedback

* Rename uniqueness constraint on user_mutes to match convention

* Remove unused account_id from where clause

* Add UserMute to NewTestDB

* Update test/envparsing.sh with new and fixed cache stuff

* Address tobi's review comments

* Make compiledUserMuteListEntry.expired consistent with UserMute.Expired

* Make sure mute_expires_at is serialized as an explicit null for indefinite mutes
