Allow collection admins to define the list of ranks relevant for their collection

[m-r-c]

When creating a new profile, the editor can manually construct the hierarchy if the name they entered is not matched. However, the hierarchy requires a rank for each level, and the list of available ranks is currently hard-coded.

The collection admin should be able to create a list of ranks that is relevant for their collection.

From an eFlora perspective, the capability to manually construct the hierarchy within a collection will be handled by the NSL alternate tree functionality.

If this issue is solved then #494 is no longer required.
