* Adds more PSP restrictions
* Update test fixtures
* Updates PSP to be conditional on initContainer
- The proxy-init container runs as root and needs the PSP to allow this
user when there is an init container.

`linkerd check`, the web dashboard, and Grafana all perform version
checks to validate Linkerd is up to date. It's common for users to
seldom execute these codepaths. This makes it difficult to identify what
versions of Linkerd are currently in use and what environments it is
being run in, which helps prioritize testing and backports.
Introduce a `heartbeat` CronJob to the default Linkerd install. The
cronjob executes every 24 hours, starting from 5 minutes after
`linkerd install` is run.

* Add control plane and CNI PSP and RBAC resources
* Add the '--linkerd-cni-enabled' flag to the multi-stage install subcommands
This flag ensures that the NET_ADMIN capability is omitted from the control
plane's PSP during 'install config' and the proxy-init containers aren't
injected during 'install control-plane'.
