Tag system for templates

[tcompa]

This requires further definition and use cases (cc @jluethi in case you have time).

High-level:

• Admin defines which tags are allowed.
• Template owner can set tags
• Everybody can use tags for searching

[jluethi]

My split would be: workflow description is free text & part of fuzzy search. Tags are more focused descriptions. Things like "This is for a specific microscope" belong in the description

Possible tags are admin-defined, preferably with some defaults already specified (which the admins could remove, but which would exist by default on a new server & which thus are useful for our central template repository).

Default tags I'd consider:

• Core
• Experimental
• HCS
• Lightsheet
• EM

Can tags be exported with a workflow, but that be made robust so that if it's reimported, only available tags are applied? Kind of like an optionally imported description of sorts.
