Assign tags to package record

Purpose: To display, assign, unassign, and output tags associated with individual Package records within the FOLIO eholdings app.

As a staff person
I want to be able to assign, unassign, view, and output tags in a FOLIO eholdings app's package record
So that I can categorize records for filtering and reporting purposes.

Background
Tags are meant to be labels that can be assigned to individual data records in various FOLIO apps. Tags will be used as a visual indicator in the record, to gather records in some way, and to facilitate reporting. This is a cross-app “helper app.” Github repo: https://github.com/folio-org/ui-tags

Requirements

• Display Tags accordion only on custom and managed package with IsSelected = True for a package
• Display Tags accordion in position below package name
• Default Tag accordion to open
• Display a multi-select dropdown that allows a user to add an existing tag, create a tag or remove a tag to/from a record
• Badge indicates in real-time number of tags assigned to record
• Given the lack of synchronization between central tags list and eholdings tags. If a tag is deleted or edited via the central tags list AND eholdings tags has no clue then eholdings may not be able to honor update and will continue to send the unchanged tag to central tags list.
