Enable write in option for directives

[mariliasoaresTW]

Business Context:

I want to enable directives on chapter's allegations to be added manually, similar to what we enabled on #272

As an NOIPM employee I want to be able to add new NOPD directives when adding an officer allegation So that I don't have to do a workaround when there's no existing directive I want to add that isn't in the list

In Scope

1. Update officers-allegations handler to accept directives that weren't already created (by allowing to write in a directive and linking it to a chapter) - database schema updates - this will require a new directive table to be created.
2. Creating a directive dropdown on the allegations page with the existing directives.
3. On the same dropdown, allow users to add new directives by writing in - same behavior as adding a new chapter.
4. Display the selected directive in the expansion panel of the added allegation

Out of Scope - to be done on #294

1. Update the search to remove the directive keyword search and allow searching only by selecting a rule or paragraph, using the existing dropdown list.

2. Update the db to remove the directives column on the allegations table and remove it from the table on the frontend

Open Questions

Acceptance Criteria

1. Scenario: Given I am adding and allegation to a case When I select a rule Then I can select a directive for the allegation from the drop down OR add a new directive by writing them in

You'll want to check the letter template as well, since it may change the template value for directive in the letter. And you may need to add the join to the directives table in the query for referral letter data

I added a directives.csv to localstack-seed-files in instance-files-noipm, so it should auto-load into localstack when you do an down and up with noipm instance files, but I didn't upload it to s3 (we'll need to put it in noipm-seed-files in both our account and NO's account eventually) so that if there are any changes necessary they can be made in instance-files before uploading
