Stacks v1 CLI / kubectl plugin: build, push, init commands

[jbw976]

Initial DevOps tooling to build Stacks, push Stacks to a registry, and init the scaffolding for new Stacks.

Part of the 0.3 release

Why? What problem are we solving with this epic?

Stacks can be used to extend the functionality of Crossplane with new types of infrastructure and applications. The experience for creating and publishing a stack is very manual at this point, so we can provide some automation and user experience around this process. This will facilitate the adoption of Stacks by the community and make it easier for more people to create their own.

What does it look like when we're done?

• The general user experience will be described in a design 1-pager
• Users will have an automated experience around:
  • initializing a new repo with the scaffolding for creating a stack
  • building a stack
  • publishing a stack
• kubectl plugin (e.g. bash script)
• only have limited config: name; limited support for patterns; kubebuilder v2.0 projects

How could this be demonstrated?

1. Crossplane user reads the blog post describing this new functionality
2. Click through to the updated user guide
3. Try out the updated example(s)

For example:

• building the wordpress stack
• publishing the wordpress stack
• init a new hello-world stack as part of example so new users can get started quickly

What is dev UX, e.g. CLI commands and usage?

TBD

Relative to #572 , we are thinking that this epic is the lower priority of the two. I am planning on working on #572 first before starting this one; I am planning to only do work on this epic before finishing #572 if it seems like it will help me finish #572 faster.
