Use DIBB bet template to draft a proposal for Test Platform/DevEx investment in mwcli (i.e. technical contributions and assisting product management).

Discuss how this investment could help accomplish these DevEx goals:

• simplifying local development environments, esp for new volunteers and staff
• extension/skin dependency management (using extension.json)
• common environment provisioning in
  • local development environments
  • CI environments
  • patchdemo environments
• remote development environment (e.g. develop on patchdemo)

The proposal should be on wiki at mediawiki.org so as to include @Addshore (the creator of mwcli) and other volunteers.
