adminguide/accounts.rst

• LDAP: Working with Shapeblue awhile back it was determined that when using linkaccounttoldap that ldap.search.group.principle is required. Wanted document this as it may help someone else down the road.

adminguide/virtual_machines.rst

• Creating SSH Keys: Added Documentation on how to do this from UI
• Resetting SSH Keys: Added Documentation on how to do this from UI

adminguide/virtual_machines/user-data.rst

• Fixed Nav: All of User-Data and Meta-Data was nested under the SSH Keys Section.
• Creating UserData: Added Documentation on how to do this from UI
• Resetting UserData: Added to documentation. Cloudstack has a broken a doc_help mapping for this and no documentation existed. This should address the broken link: https://docs.cloudstack.apache.org/en/latest/adminguide/virtual_machines.html#resetting-userdata

note please @scottsignal , this will only be added to the documentation when v21 is released. Hope that is alright with you. If not, please rebase on an earlier branch.
