Different lints for Pull vs Push members

[nschonni]

Some people in the organization are added to read only groups so they can be assigned tasks, but not pull permission because they might not be coding at all.

If they only have Pull permission to the repo, the 2 factor isn't really important (good idea though), but a full profile should be required.

The current assumption is that the "all" users have pull permission to the repo.
edit: updated title to reflect pull = read, and push = write
