snap_sched_ui_create_retention_both_fails

Description of problem:
'Add retention policy' box exists in Snapshot schedule Create. It is enabled, so can be used to add retention policy during snap schedule create. But if used, upon 'Create Snapshot Schedule' button click, generates an error as in attached screenshot.

Error : "Failed to add retention policy.....:No schedule found"

This error could be expected. Because even in CLI, we need to first create schedule, and then for same path we can apply retention policy that gets applied to all existing schedules of same path.

But as we have 'Add retention policy' enabled for use, during create, any user can use it and face above circumstances. So, we should with either support use of this retention button or remove it or disable it, as appropriate.

Also, when "Failed to add retention policy.....:No schedule found" appears with 'Create snapshot schedule' click, if 'Add retention policy' was used, we also notice that, schedule gets created in background and an entry is made in list of schedules(refer screenshot). 

But for user, considering error seen as '"Failed to add retention policy.....:No schedule found"' , he may remove retention policies and try again 'Create snapshot schedule' button click, which generates error stating 'Path already exists'.

So we displayed error as '"Failed to add retention policy.....:No schedule found"' but have created the schedule in background, no notification for creation either.
