Once OCM fully supports HTPasswd as a regular IDP, it needs to be added to the OCM website along with the rest of the IDPs. Each cluster should support multiple HTPasswd IDPs and each HTPasswd IDP should support multiple user:password entries.

This story deals with allowing a user to select and delete multiple users on the 'Edit HTPasswd users' page.

Location in OCM UI: Cluster Details > Access Control > Add IDP:  Add HTPasswd IDP
