IQSS/9247 Curation Status Updates

[qqmyers]

What this PR does / why we need it: This PR extends the External/Curation Status Label mechanism:

• adding tracking of who creates the status label and when,
• keeping a history of past statuses
• updating the CSV report to include the creation time and assigner of a status
• updating the getCurationStatus api call to return a JSON object for the status with label, assigner, and create time
• adding an includeHistory query param for these API calls to allow seeing prior statuses
• adding a facet to allow filtering by curation status (for users able to set them)
• adding the creation time to solr as a pdate to support search by time period, e.g. current status set prior to a give date
• standardizing the language around 'curation status' vs 'external status'
• adding a 'curation-status' class to displayed labels to allow styling
• fixing a bug in the notification display that would show the current status rather than the status as of the notification time
• improving the email message to include a link to the dataset and the name of/link to the collection its in.

Which issue(s) this PR closes:

• Closes Feature Request/Idea: Make Curation Status Labels filterable #9247

Special notes for your reviewer:

Suggestions on how to test this: Verify that curation statuses can be set/removed when the overall curation status mechanism is enabled. Verify that the status can be removed. Verify that status is removed at publication. Verify that the /api/datasets/{id}//curationStatus and /api/datasets/{id}/listCurationStates api calls return correct results, with and without the ?includeHistory=true flag. (Most of this is tested in IT tests as well.)
