Disable initializers by default
The API group driving this field is not enabled by default, and it does not appear that these will progress beyond the alpha phase.
Remove the admission plugin from default configurations.

```release-note
The alpha `Initializers` admission plugin is no longer enabled by default. This matches the off-by-default behavior of the alpha API which drives initializer behavior.

Usage of names containing uppercase characters returned by calls to
gethostname and getfqdn in requests to apiserver related to nodes
results in 404 errors. Node names are lowercase in K8s itself so charms
should make sure to use lowercase names well as it results in errors.
pkg/util/node/node.go has code to convert hostnames to lowercase in
GetHostname and that function is used to form node names.

kubernetes-worker juju charm: Added support for setting the --enable-ssl-chain-completion option on the ingress proxy.

juju: Make kubernetes-master status handling more robust
**What this PR does / why we need it**:
This fixes a charm hook failure that can occur after restarting kubernetes-master units in Juju-based Kubernetes deployments.
This should also hopefully make our status handling in kubernetes-master more robust in general, by making sure all of our `blocked`, `waiting`, and `active` status messages are handled in one place, on hook exit.

Update all script shebangs to use /usr/bin/env interpreter instead of /bin/interpreter
This is required to support systems where bash doesn't reside in /bin (such as NixOS, or the *BSD family) and allow users to specify a different interpreter version through $PATH manipulation.
