Revert default service-cidr config on kubernetes-master charm

**What this PR does / why we need it**:

This reverts the default service-cidr config in the kubernetes-master charm.

A while back, we changed the default service-cidr in the kubernetes-master charm from `10.152.183.0/24` to `10.152.0.0/16`. In testing, we have found that the charms don't handle this change well, so we are reverting it until we can make the change more safely.
