Split out CI and deployment pipelines

This should do a few things:

1) Make it easier to see only the pipeline runs that are doing actual
deployments to environments. Currently these are intermingled with CI
test runs.

2) Disable the DB migrations check on the deployment pipeline. This
check is used for CI only, because in some situations we might expect
(and want) it to fail.
