Enhance logging

For my own sanity, the bot must output additional details when performing operations. For example,

* Any time the bot is trying to add a user to the team, if the user doesn't exist and/or is "dormant" the sync bot must clearly state so. At this point in time, the bot does output users with Issues... However, additional clarity could be had by clearing separating/categorizing what "type" of issues are found with the user. More thoughts are needed on this.
* If an Org has not granted the app the proper permissions, some operations will fail. The logs must clearly call attention to the fact that the bot does not have permissions, and that folks must poke the Org Owners to update said permissions (by requesting the updated permissions request from the bot).
