[MRM-1362] Add simple 'CRUD' pages for project-level metadata along with a "generic metadata" plugin

o removed project metadata custom tag
o enable delete of generic metadata properties
o added unit tests for adding and deleting properties
o clear facet properties read from file before doing the update so that removed facet properties are not retained when updating project version metadata
