Support addon providers such as CAAPH

[nikParasyr]

User Story

As a operator I would like to be able to deploy addon providers such as CAAPH using the operator

Detailed Description

We are looking to slowly move to the operator instead of installing the various capi controllers via clusterctl. We will start testing with the next release (and the helm chart improvements). One piece that is missing for us is support for addon providers. Currently there is only caaph ( still in early alpha releases )and capi added support for clusterctl just recently in 1.5.0.

Anything else you would like to add:

Note 1: not having support for addon providers is not a blocker for us, but it would be very nice if there will be support in the future to have everything capi related deployed by the operator
Note 2: I could try to find some time to work on this ( have contributed to some other capi projects before ), but i would appreciate some initial pointers in what needs to be done in order to support this

Thank you :)

Agree this would be an excellent feature to see.
If someone deploys the CAPI operator and wants to manually add an addon such as CAAPH, what would be the supported way to accomplish this?

Seems like that would a great feature as well. Curious as to David's question too.

There is no supported way right now, users can manually apply the manifests. We plan to release a new version of the operator early next week and start working on v1alpha2 version of the API #190, addon provider can be added to the new API version, it shouldn't be a complicated change assuming it is similar to other providers.
