For FIPS support we need to be able to tell when an OCP cluster has been deployed in FIPS mode (it's a day one operation). This patch adds the `IsFipsCluster` function that checks if FIPS is enabled or not. The way to do that is checking the install-config YAML that is stored in the cluster-config-v1 Config Map. If we find the fips key, and it has the true value, then it's deployed in FIPS mode, otherwise it isn't.
