and container image can be built.

Based on the review comments addressed the following,
- Moved away from having to update the pod with volumes
when a new Ceph cluster is added for provisioning via the
CSI driver
- The above now used k8s APIs to fetch secrets
- TBD: Need to add a watch mechanisim such that these
secrets can be cached and updated when changed
- Folded the Cephc configuration and ID/key config map
and secrets into a single secret
- Provided the ability to read the same config via mapped
or created files within the pod
Tests:
- Ran PV creation/deletion/attach/use using new scheme
StorageClass
- Ran PV creation/deletion/attach/use using older scheme
to ensure nothing is broken
- Did not execute snapshot related tests

This commit provides the option to pass in Ceph cluster-id instead
of a MON list from the storage class.
This helps in moving towards a stateless CSI implementation.
Tested the following,
- PV provisioning and staging using cluster-id in storage class
- PV provisioning and staging using MON list in storage class
Did not test,
- snapshot operations in either forms of the storage class

issue #217
Goal
we try to solve when csi exit unexpect, the pod use cephfs pv can not auto recovery because lost mount relation until pod be killed and reschedule to other node. i think this is may be a problem. may be csi plugin can do more thing to remount the old path so when pod may be auto recovery when pod exit and restart, the old mount path can use.
NoGoal
Pod should exit and restart when csi plugin pod exit and mount point lost. if pod not exit will get error of **transport endpoint is not connected**.
implment logic
csi-plugin start:
1. load all MountCachEntry from node local dir
2. check if volID exist in cluster, if no we ignore this entry, if yes continue
3. check if stagingPath exist, if yes we mount the path
4. check if all targetPath exist, if yes we binmount to staging path
NodeServer:
1. NodeStageVolume: add MountCachEntry on local dir include readonly attr and ceph secret
2. NodeStagePublishVolume: add pod bind mount path to MountCachEntry and persist local dir
3. NodeStageunPublishVolume: remove pod bind mount path From MountCachEntry and persist local dir
4. NodeStageunStageVolume: remove MountCachEntry from local dir
as the socket directory will be created
inside the container no need to follow
the plugin name in for the directory
creation, this will also reduce the code
changes if we want to change driver name.

This commit reverts the initial implementation of the
multi-node-multi-writer feature:
commit: b5b8e46460
It replaces that implementation with a more restrictive version that
only allows multi-node-multi-writer for volumes of type `block`
With this change there are no volume parameters required in the stoarge
class, we also fail any attempt to create a file based device with
multi-node-multi-write being specified, this way a user doesn't have to
wait until they try and do the publish before realizing it doesn't work.
