feat: embed tkn tasks in func binary

[matejvasek]

Changes

• Embedded Tekton tasks in the func binary. This removed dependency of files hosted in Github, making func more viable for air-gaped envs. For now I embedded them as plain string, in future I would like to change them into Go struct literals.
• Since the tasks are no longer present as yaml files in GH I added new hidden sub-command func tkn-tasks that lists these tasks. This is good for information purposes or in cases when the task must be installed in cluster for e.g. OCP Web Console build.

Looks good to me. Apart from the large embedded yaml, it's a nice cleanup as well.

Looks good to me. Apart from the large embedded yaml, it's a nice cleanup as well.

@lkingland I plan to translate these strings to Go struct literal for type-safety in future.
