Feature Overview (aka. Goal Summary)  

Provide the bootstrap with specific instructions to execute through ignition configs by passing configuration options to the bootstrap node

Goals (aka. expected user outcomes)

Pass options via the install config manifest all the way to the bootstrap node by setting ignition config with the appropriate values

Requirements (aka. Acceptance Criteria):

• Users are able to pass options via the install config manifest
• Provision in the bootkube to accept these flags and perform accordingly

Background

ARO requires specific settings such as network settings to be passed through the ignition configs at boot time. These configurations include things such as: important IPs for the image-registry that include all the mirrored OCP releases inside the Azure platform, etc. 

Logging agent MDSD is also sent ignition config.

Documentation Considerations

This feature should be invisible to the OCP user.

Implementation Considerations

Terraform is used for all ignition booting (revisit after CAPZ)
