Split off cli into separate binaries (#37)
* 🎨 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. Fixes #14 * 🤖 Add provider bin to releases * ⚙️ Handle signals * ⚙️ Reduce buildsize footprint * 🎨 Scan for providers also in /system/providers * 🤖 Run goreleaser * 🎨 Refactoring
