When IPv6-only network mode is enabled and when mons are configured to
listen only on msgrV2 port, Rook has to add the port to the mon
--public-bind-addr in order to force mons to stop listening on the
msgrV1 port. This can cause problems for IPv6 clusters where adding
':<port>' to the end of an IP addr looks like a valid IPv6 address.
In IPv6 mode, Rook needs to set this to '[<ip>]:<port>' with the
brackets to be a non-ambiguous IPv6 address.
In IPv4 mode, Rook needs to keep its existing behavior. IPv4 mode should
also continue to be the defualt assumption if the network config isn't
specified.
If 'dualStack: true' is specified, Rook is informed that the environment
is dual stack, but Rook doesn't know which IP family to expect from the
pod IP. In this scenario, it is safest for Rook not to apply the port,
since assuming either IPv4 or IPv6 format could be incorrect. In this
scenario, mons may still listen on msgrV1 ports, but this is preferable
to an environment where mons perpetually crash.

(cherry picked from commit 573a47e736)
The mon was listening on both v1 and v2 ports inside the daemon
even though the service endpoint would not redirect any traffic
to the v1 port. When msgr2 is required, disable the mon from
listening on the v1 port for reduced security footprint.

Change how Rook detects network CIDRs for Multus networks. The IPAM
configuration is only defined as an arbitrary string JSON blob with a
"type" field and nothing more. Rook's detection of CIDRs for whereabouts
had already grown out of date since the initial implementation.
Additionally, Rook did not support DHCP IPAM, which is a reasonable
choice for users. And more, Rook did not support CNI plugin chaining,
which further complicates NADs. Based on the CNI spec, network chaning
can result in any changes to network CIDRs from the first-given plugin.
All these problems make it more and more difficult for Rook to support
Multus by inspecting the NAD itself to predict network CIDRs. Instead,
it is better for Rook to treat the CNI process as a black box. To
preserve legacy functionality of auto-detecting networks and to make
that as robust as possible, change to a canary-style architecture like
that used for Ceph mons, from which Rook will detect the network CIDRs
if possible.
Also allow users to specify overrides for CIDR ranges. This allows Rook
to still support esoteric and unexpected NAD or network configurations
where a CIDR range is not detectable or where the range detected would
be incomplete. Because it may be impossible for Rook to understand the
network CIDRs wholistically while residing only on a portion of the
network, this feature should have been present from Multus's inception.
Improving CIDR auto-detection and allowing users to specify overrides
for auto-detected CIDRs rounds out Rook's Multus support for CephCluster
(core/RADOS) installations. No further architectural changes should be
needed for CephClusters as regards application of public/cluster network
CIDRs for Multus networks.

Mons that are configured on msgr1 will be using the v1 port
in the csi driver since only one port is allowed in the configmap.
To allow mons to be started on v2 while keeping quorum with the
v1 mons, the v1 mons must continue running on the v1 port.
So even if msgr2 is required, allow existing v1 mons to continue
running on that port.

If the host network setting is changed in the cluster CR,

Allow specifying daemon startup probes where we also allow configuring
liveness probes. Startup probes allow Rook to tolerate when Ceph daemons
occasionally take a long time to start up while not also making
Kubernetes liveness probes slower to detect runtime failures of daemons.
Startup probes are beta in Kubernetes 1.18, so we should not enable
probes by default for earlier Kubernetes versions.

The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

By setting the working directory of a Ceph daemon to the log direcor
(which is bindmounted to the host), we can ensure that the coredumps
will be available.
On CentOS 7 **only**, the kernel is configured with:
```
cat /proc/sys/kernel/core_pattern
core
```
which means that the coredumps will end up in the process working
directory and will be named "core".
On CentOS 8, everything is different and this won't work but still
CentOS will be able to consume this and changing the working directory
is harmless.

zone, while keeping two replicas of the data in each of the data
zoens.

This commit allows us to configure status check for each daemon:
* "mon": health check on the ceph monitors (quorum)
* "osd": health check on the ceph osds
* "status": ceph health status check
Each check is controlled by the following settings:
* disabled: whether to disable the check (default: false)
* internal: interval to run the check
* timeout: only valid for mons, is the timeout for unresponsive mon
before failling over.
Example to disable the status health check:
```yaml
healthCheck:
daemonHealth:
status:
disabled: true
```
As part of that, pod's livenessprobe can now be configured via the
following settings:
* disabled: whether to enable or not
* probe: override the current probe in place by a new one
```yaml
