Move out cmd pieces and split into its own package. Also make sure we reload
plugins before bootstrapping nodes.
Also commons out the agent configuration in a specific YAML file.
* 🎨 Split off cli into separate binaries
This commit splits off the cli into 3 binaries:
- agent
- cli
- provider
The provider now is a separate component that can be tested by itself
and have its own lifecycle. This paves the way to a ligher c3os variant,
HA support and other features that can be provided on runtime.
This is working, but still there are low hanging fruit to care about.
