Problem statement

Currently we install UCX to a single workspace at a time. This is unsustainable for accounts with 10s and 100s of workspaces.

Proposed Solution

Allow admins to run the installer as account admins and install it to all the workspaces in a given account at once.

• Perform CLI auth to login to the account.
• Run the installer.
• Select the option to install to all workspaces
• UCX is installed to all workspaces.
• We place a config.yml with a list of all workspace ids
• we create workspaces.json with workspace id to workspace name mapping
