VSA settings: [FE] Migrate add / edit value streams to settings page
### Proposal We're moving the VSA value stream configuration / settings from the modal to a standalone settings page. * This issue is targeted at moving the existing functionality i.e. screenshots below minus the projects / timespan and labels sections. #### Vision | New | Edit | | ------ | ------ | | ![VSA_G_proposal_A_2_-_new](/uploads/14e7be2f6e96c92ad93056c89abfee4a/VSA_G_proposal_A_2_-_new.jpg) | ![Screenshot_2022-11-01_at_10.13.30](/uploads/23b0f12ab260fc706e9dfc788fecc66f/Screenshot_2022-11-01_at_10.13.30.png) | | ![create--mobile](/uploads/50cbecc745f736689443da760f6282b0/create--mobile.jpg) | ![Screenshot_2022-11-01_at_10.20.43](/uploads/317e60017db68f8f08aac817f774d899/Screenshot_2022-11-01_at_10.20.43.png)| #### Implementation guide * [ ] Move create value stream functionality to a new page `/groups/gitlab-org/-/analytics/value_stream_analytics/value_streams/new` * [ ] Move edit value stream functionality to a new page `/groups/gitlab-org/-/analytics/value_stream_analytics/value_streams/<value-stream-id>/edit` * [ ] Clean up old VSA vuex store + update feature tests and jest tests * [ ] Move action buttons to a sticky footer #### Additional Notes * We should be able to re-use the same form for creating and editing * Create value stream: should redirect to the new value stream on success (`/groups/gitlab-org/-/analytics/value_stream_analytics/value_streams/<new-value-stream-id>` * Edit value stream: should stay on the edit page on success * The action buttons should be added to a sticky footer (see images) * Ignore `selected projects`, `time period` and `filters` fields for now
