New subcommands to support Upbound Spaces

[tnthornton]

Description of your changes

Introduce a new set of management APIs for working with Upbound Spaces.

New subcommands:

• up space init - Initializes an Upbound Space in the target cluster. As part of installation, we optionally install required prerequisites.
• up space upgrade - Upgrades the current installation of an Upbound Space in the target cluster.
• up space destroy - Deletes the Upbound Space installation from the target cluster (note: this deliberately orphans the Crossplane configurations and resource instances)

Removes subcommands:

• up upbound install
• up upbound upgrade
• up upbound delete

I have:

• [X] Read and followed Upbound's contribution process.
• [X] Run make reviewable to ensure this PR is ready for review.

I'm not sure I should be the final approver on a change this big, but it looks good to me. Thanks!
