Add params and mount options for a trusted-ca and ca config map

[ralphbean]

Observe how the build-definitions tasks have params to use a trusted-ca and a configmap. Those get mounted and used so that the tasks will trust the cluster's self-signed cert if it has one. The release pipeline tasks don't have this, which makes testing in a local kind cluster using the internal kind registry difficult/impossible.

There was a pattern we used for enabling self-signed certificates for all tasks where we needed them. It required introducing the volume mount for the certificate and then mounting it to the path relevant to the image running the relevant step. Here's an example:
