DPL-890-2 Add a new UI and the endpoint to allow the creation of new prefixes

[Sangeetha-Bheeman]

User story
As PSD developer I want to be able to add prefixes in UI to be stored in Postgresql database instead of a config file so I don't have to redeploy baracoda every time a new prefix is needed.

Who are the primary contacts for this story
Sangeetha, Steve

Who is the nominated tester for UAT
Sangeetha

Acceptance criteria
To be considered successful the solution must allow:

• users to create a new prefix from UI.
• the prefixes must be stored in and retrieved from a postgresql database.
• remove the need to redeploy baracoda for adding prefixes.
• the application should continue to work as expected without any loss of service to the users.

Dependencies

• DPL-880 Baracoda to add/remove/retrieve prefixes using UI backed in database (S=L; C=M) #417
• DPL-880-1 Add a new postgresql table for storing the prefixes instead of a config file to avoid deployment of baracoda for adding a prefix #470
• DPL-880-3 Add a new UI to show all prefix data and also provide the ability to mark a prefix as inactive and not delete. #472
