[Meta] Uptime public UI enhancements for Synthetics service

[dominiqueclarke]

This issue is to track all the requirement/enhancements we need in Kibana uptime public code to interact with synthetics service and respective server code in the uptime app.

Feature flag implementation

• [Uptime] [UI Monitor Management] Hide all corresponding pages and new features behind a feature flag #408
  This could be a new feature flag, for example, xpack.uptime.unsafe.service.enabled or an existing service-only key that we will set directly for our private beta customers xpack.uptime.unsafe.service.url.

Add / Edit Monitors:

• [Uptime] UI Monitor Management Stub Add Monitor Page #409
  Add a new page to create and save a heartbeat monitor. Existing components and state management from the Elastic Synthetics Integration should be reused where possible. Saving a monitor should save the configuration to saved objects.
• [Uptime] Add Edit Monitor Page #412
  Add a new page to edit a monitor based on id will need to define a scheduled task using Kibana task manager, which will run periodically to push monitor configurations to the synthetics service
• [Uptime] Display available locations in add and edit monitor flow #416
• Change frequency in Monitor Management to minutes #428
• Remove Suite Support / ZIP URL in Monitor Management for Tech Preview #427

Creation flow, save redirect

• Redirect the user to the appropriate place after saving a monitor (Closed with [Uptime] Add basic ui monitor management table, basic monitor editing, and basic location selection kibana#120038)

Management page, "new" monitors

• [Uptime] UI Monitor Management Monitors Table - "New" Monitors #413
  We need to pass an API key generated by kibana to the synthetic service, that will be used by heartbeat to communicate with elasticsearch.

Validation

• [Uptime] Add validation for UI Monitor Management Add Monitor Page - Locations kibana#120798

Monitor Management Table

• [Uptime] Add Enabled Toggle to UI Monitor Management table #415
• [Uptime] Add Locations to the UI Monitor Management Table kibana#121006

One shot mode

• Implement one shot mode to test monitor configuration](Implement one shot/test now mode while adding/editing monitors #437

Run Now/Trigger now mode

• Implement run now/trigger now mode in UI #440

Creation flow dependencies

• Ensure Elastic Synthetics package and index templates are created is installed before loading the add monitor
  Before a monitor can successfully be created, we must ensure the mappings are created and the API key exists

Resolved by elastic/kibana#119727 and Fleet auto upgrade flow

Edit flow, ensure package spec is up to date

• Ensure that the latest synthetics integration package is installed when editing a policy
  Just like the creation flow, we must ensure that the latest version of the integration package is installed when editing a monitor.

Resolved by elastic/kibana#119727 and Fleet auto upgrade flow

@dominiqueclarke I'm going to pop this onto the 8.0 board so it's easier to find
