Implement Release workflow

[alexandrebrg]

What needs to be done

• Create a workflow with release drafter to have auto-generated releases
• A new release should build RIK and add binary assets for amd64 in the release
• PR should have labelled based on their name

Why it needs to be done

• Ability to freeze a version of the code that is working
• Better visibility over feature / fix pushed between releases

First release content:

---

This first release bring the basic functionalities of RIK, and is stable enough to be released. You can learn more about it through the README and through our documentation.

What features are available ?

Main purpose:

• Orchestrate workloads around a multi-node cluster

Components:

• Controller binary is used to manage the state of the cluster, it's the only source of truth
• Scheduler binary is used to determine the appropriate node for a workload
• Scheduler component is able to re-scheduler a workload when a worker is unhealthy
• Riklet binary is a worker, it receives workload from scheduler
• Rikctl binary can be used to manage your cluster
• Inter component communication is defined with protobuf

Workloads:

• Workloads supported are pod and function
• function workloads expect to be bring a custom rootfs and linux kernel in order to run
• pod workloads are containers which support containers from hub.docker.com
