Check nil pointer in predicates.go

Should check if the pointer is nil in func filterVolumes as is done in [func predicate](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/algorithm/predicates/predicates.go#L279).

No need to log empty string in predicates.go

If `pvcName` is empty, we don't need to log it.

c9a60e2d2c Rephrase 'pv not found in cache' warnings.
When kubelet starts a pod that refers to non-existing PV, PVC or Node, it
should clearly show that the requested element does not exist.

Previous "PersistentVolumeClaim 'default/ceph-claim-wm' is not in cache"
looks like random kubelet hiccup, while "PersistentVolumeClaim
'default/ceph-claim-wm' not found" suggests that the object may not exist at
all and it might be an user error.

41ed85479a move predicates into library (address #12744)
DONE:
1. refactor all predicates: predicates return fitOrNot(bool) and error(Error) in which the latter is of type
	PredicateFailureError or InsufficientResourceError. (For violation of either MaxEBSVolumeCount or
        MaxGCEPDVolumeCount, returns one same error type as ErrMaxVolumeCountExceeded)
2. GeneralPredicates() is a predicate function, which includes serveral other predicate functions (PodFitsResource,
        PodFitsHost, PodFitsHostPort). It is registered as one of the predicates in DefaultAlgorithmProvider, and
        is also called in canAdmitPod() in Kubelet and should be called by other components (like rescheduler, etc)
        if necessary. See discussion in issue #12744
3. remove podNumber check from GeneralPredicates
4. HostName is now verified in Kubelet's canAdminPod(). add TestHostNameConflicts in kubelet_test.go
5. add getNodeAnyWay() method in Kubelet to get node information in standaloneMode

TODO:
1. determine which predicates should be included in GeneralPredicates()
2. separate GeneralPredicates() into:
	a. GeneralPredicatesEvictPod() and
	b. GeneralPredicatesNotEvictPod()
3. DaemonSet should use GeneralPredicates()

2d436ff080 Scheduler predicate for capping node volume count
For certain volume types (e.g. AWS EBS or GCE PD), a limitted
number of such volumes can be attached to a given node.  This commit
introduces a predicate with allows cluster admins to cap
the maximum number of volumes matching a particular type attached to a
given node.

The volume type is configurable by passing a pair of filter functions,
and the maximum number of such volumes is configurable to allow node
admins to reserve a certain number of volumes for system use.

By default, the predicate is exposed as MaxEBSVolumeCount and
MaxGCEPDVolumeCount (for AWS ElasticBlocKStore and GCE PersistentDisk
volumes, respectively), each of which can be configured using the
`KUBE_MAX_PD_VOLS` environment variable.

Fixes #7835
