oc_validate should error if a parameter that is used is not defined in the parameters array about cas-pipeline

It sounds like we should add a check to the lint macro that does something along the lines of an array equality check between

oc process --parameters -f template.yml | awk 'NR>1 { print $1 }' | sort | uniq

and

awk 'match($0, /\$\{.+\}/) { print substr($0, RSTART+2, RLENGTH-3) }' template.yml | sort | uniq

since the oc cli doesn't actually check if templates are well-formed, and since we are currently validating the configured templates for schema conformance after interpolation so we don't discover template errors like this.

We could also consider adding yamllint as a preflight check to see if the template file is well-formed, though that wouldn't directly solve for this specific use case.
