[Uptime] Add new context for uptime - #34006

Summary

In the initial version of Uptime, we had several fields that were shared from the top-level application component all the way down to the most nested component in the UI. This is exactly what contexts are designed for, so going forward we should make use of a context to avoid the need for sharing so many props and & UptimeCommonProps everywhere.

The primary goals of this patch are as follows:

• Delete UptimeCommonProps and the need to pass {...this.props} to so many child components
• Add a new UptimeContext to the UI to provide these important global values

This PR is WIP.

Overview

There are 3 main changes in this PR:

• Altogether removal of *Query components
  • Any business logic these components contained has been moved to the functional components
• Addition of an UptimeContext for top-level global props
• Removal of general-purpose interfaces and the need to pass entire state/props from top to bottom

Additionally, the GraphQL queries have been moved to a dedicated directory outside of the components folder.
