Rewrite command discovery and command list

[tomdye]

Enhancement

When working on the command list POC I came across issues with the current CLI implementation which have been raised. I feel that it is time to rewrite the command discovery portion of the CLI to make it easier to combine installed commands, available commands and built in commands into a single output that the user can work with. I believe that our cli interfaces are stable enough to support this rewrite and that it will make future changes to the cli much more straight forward to implement.

Planned changes

• Remove cli-create-app dependency
• Present built in commands via an all.ts or similar, removing the need to find and load the,
• Search for installable commands and merge correctly with installed commands
• Make installed command list available to build in functions so they do not have to find them themselves
• Upgrade dependencies
• Indicate to the user which packages can be updated when displaying the command list
