Add dynamic deadlines to gitaly

See merge request gitlab-org/gitlab!21492

Accept Envelope-To header

Closes #37359

See merge request gitlab-org/gitlab!22354

This makes sure that the deadline we set on a gitaly call never
exceeds the request deadline.

We also raise an exception if the request deadline has already been
exceeded by the time we're trying to make a Gitaly call.

These deadlines don't apply when calling gitaly from Sidekiq.

We do this by storing the start time of the request in the request
store on the thread (using the RequestStore).

The maximum request duration defaults to 55 seconds, as the default
worker timeout is 60 seconds. But can be configured through
gitlab.yml.

GKE network and subnetwork dropdowns

This MR implements two dropdown fields used by the GKE cluster configuration form: network and subnetwork. This MR only contains the dropdown component implementations but it does not integrate the dropdowns in the form. The purpose is to keep the size of the MR manageable. 

To test the dropdowns, please use the following integration MR https://gitlab.com/gitlab-org/gitlab/merge_requests/22344

Frontend - Resolve "Display in MR if security report is outdated"

See merge request gitlab-org/gitlab!20954

When the last pipeline for the target branch hadn't detected some
security issues, maybe due to jobs failed or artifacts expired, the
MR security report should be considered outdated and the pipeline needs
to be re-run. It also handles the edge case when target branch has
received more commits and the current branch needs to be updated.
