Now there is a `install` section in the config that has the fields that previously where in `c3os` but
were actually only used during install phase.
Also the k3s and c3os config were moved to the provider instead that in the global config.
This changeset also adds a `config_url` and `options` keyword in the c3os config.
Along with that the config logic is changed so the configuration is taken also from boot commands and merged in the final installed config 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.
