Creation and display of handles/permalinks (for collections, items, and media/file)

WIP at https://github.com/asulibraries/islandora-repo/tree/develop/web/modules/custom/persistent_identifiers

I submitted a PR to mjordan's persistent_identifiers module to add a handle minter: mjordan/persistent_identifiers#2

[elizoller]

This PR has been accepted allows configuration to choose which content types to apply to. It currently doesn't support minting handles for media objects or files themselves.

I just want to confirm that we would like handles on media objects. if so - i think it'll work, we just need to add the field_handle to all of the media types we want it to work on
once we do that, we can just uncomment 6935b70#diff-c629edd4149b82775911c1f1c0b36c01R183 and it'll be good to go

also worth noting i changed the persistent identifiers hdl minter to allow an override to the qualifier (because we use different qualifiers per object type). so that work is in a branch here: https://github.com/asulibraries/persistent_identifiers/tree/override_qualifier

really i need to do a fair amount of cleanup, following best practices ETC on that minter so i didn't feel it was worth pushing back to mark yet, but after go live, i'll need to make that minter better

in repo dev we decided that for now, we won't mint handles for new media, but that we will, as we migrate, keep a log of the old handles and what item they map to and update existing attachment handles to point to the parent item.

49a405c enforces that only handles are minted automatically when the hdl module is enabled
