Extend/exchange topics tagging model with robust taxonomies

[saschaben]

Currently we provide a flat tagging mechanism via the "topics" list, which is owned by each school in Ilios.

In order to meet increasing complex tagging and badging needs, this needs to be modified to provide a means of creating taxonomies of more depth.

Solution will need to allow for:

• creation of at least two levels (preferably three levels) of taxonomic hierarchy and categorization (eg. "Topics:Anatomy:Spiral Learning Level II", "UCSF49:Cluster XXX:Syndrome Y")
• creation of descriptive metadata associated with each term (this can be a single text entry value)
• custom input of values by administrative users

This will require major schema modification, update to the API, and sibling tickets in ilios/frontend to address both administration and display

Prior to launch, we need to add to the migration a tool which will destroy any values in the report table which inlcude "topics" as either subject or prepositional object. Otherwise the existing reports will blow up in the face of the user.
