Cells gdk.yml management

Overview

We want the main gdk.yml as single source of truth and let GDK update cells' gdk.ymls

Below, I have to customize cell-1's gdk.yml, :

---
asdf:
  opt_out: true
cells:
  port_offset: 12000
gitlab_http_router:
  enabled: false
hostname: gdk.test
vite:
  enabled: true
webpack:
  enabled: false
gitlab:
  rails:
    session_store:
      session_cookie_token_prefix: abcd

It will be ideal to move this to primary gdk.yml instead:

cells:
  enabled: true
  instance_count: 1
  gdk_configs: # For all cells
    vite:
      enabled: true
    webpack:
      enabled: false

  instances:
    - name: cell_1
      config: # Only for cell_1
        gitlab:
          rails:
            session_store:
              session_cookie_token_prefix: abcd

Implementation Details

• We need the ability to configure arbitrary settings for all secondary cells
• We need the ability to configure arbitrary settings for individual secondary cells

Impacted categories

The following categories relate to this issue:

• gdk-reliability - e.g. When a GDK action fails to complete.
• gdk-usability - e.g. Improvements or suggestions around how the GDK functions.
• gdk-performance - e.g. When a GDK action is slow or times out.

Steps to replicate (optional)

Proposal (optional)

Make it so that arbitary settings is propagated to all cell's gdk.yml

Environment (optional)

• Operating system name: <!-- output of `uname -a` command -->
• Architecture: <!-- output of `arch` command -->
• The contents of your gdk.yml (if any)
• Ruby version: <!-- output of `ruby --version` command -->
• GDK version: <!-- output of `git rev-parse --short HEAD` command -->
