Enhance Build pipeline with kaniko and arm capabilities

Better caching allowing us to speed up builds and reduce iteration time

At the moment quite a lot of the builds take about 10-15 minutes which is a value that should really be sped up. Adding Kaniko and using it's caching should help here by storing the intermediate image layers.

Arm architecture

Some Projects using ARM builds currently take a lot of time to build due to the emulation etc. adding ARM instances to the builder pool would help a lot here. Using more ARM docker images as lambda could also result in more cost savings down the line.
