This makes sure that the Rancher chart correctly passes the
user-provided image registry value to values.yaml. So Longhorn
will pull the CSI Driver Registrar image from private registry
if the registry is provided.

Also remove test image in images.txt and release-images.txt.
The images related to integration test will be addressed separately later.

This help to remove the extra dependency on different container image
registry. Docker Hub now holds all Longhorn components' images.
Also, users can easily pull all the necessary images to their
air-gap environment

1. Use different names for the 2 roles
(and the related role bindings)
2. Make sure the role binding namespace is the same as the
namespace where nfs provisioner is deployed

The idea is to implement a locking mechanism that utilizes the backupstore,
to prevent the following dangerous cases of concurrent operations.
1. prevent backup deletion during backup restoration
2. prevent backup deletion while a backup is in progress
3. prevent backup creation during backup deletion
4. prevent backup restoration during backup deletion
The locking solution shouldn't unnecessary block operations, so the
following cases should be allowed.
1. allow backup creation during restoration
2. allow backup restoration during creation
The locking solution should have a maximum wait time for lock acquisition,
which will fail the backup operation so that the user does not have to wait
forever.
The locking solution should be self expiring, so that when a process dies
unexpectedly, future processes are able to acquire the lock.
The locking solution should guarantee that only a single type of lock is
active at a time.
The locking solution should allow a lock to be passed down into async
running go routines.

We changed the imagePullPolicy to IfNotPresent so that user can easily
install Longhorn in air-gap instalation.
Also add a bash script for the developer to quickly change all the
imagePullPolicies back to Always so that k8s always pull the
lastest images. This will be useful when dev use the tag such as master.

The test deployment creates 4 replicas that continously, write the
current date time once a second into the file `/mnt/nfs-test/test.log`
This is a good test for an rwx volume. Since it replicates an append
only log that is used by multiple pods.

So that on a delete & recreate of the service the previous pv's still
point to this nfs-provisioner. We cannot use the hostname since the actual
host doesn't know how to resolve service addresses inside of the cluster.
To support this would require the installation of kube-dns and
modification to the /etc/resolve.conf file on each host.

This makes the nfs client use a new src port for each tcp reconnect.
This way after a crash the faulty connection isn't kept alive in the
connection cache (nat). This should allow to resolve the cluster ip to
the new destination pod ip.

Add tolerations so that nfs provisioner pod gets evicted from a failing
node after 60 second + 30 grace period (relevant for va recovery policy).
Add liveness + readyness probe, so that no traffic gets routed to a failed
nfs server. Disable device based fsids (major:minor) since our block device
mapping can change from node to node, which makes the id's unstable.

Attempting to use longhorn with NFSv3 for backuip causes errors related to rpc.statd, which is not managed by longhorn processes. Longhorn works properly with NFSv4 servers only.
