allow convert to default on a per object basis
`kubetl convert` needs to distinguish between cases where a user specifies a version (use this at all cost) and cases where it doesn't (for each object, find the best version to convert to). This allows that to happen.

Fix format string in describers
**What this PR does / why we need it**:
This PR fixes bug in the Vsphere Volume Source and other describers.
Before this fix `kubectl describe` could show something like this:
```
Source:
Type: vSphereVolume (a Persistent Disk resource in vSphere)
VolumePath: StoragePolicyName: %v
FSType: volumes/PVDISK_001
%!(EXTRA string=ext4, string=)Events: <none>
```
It happened because format string was accidentally split to 2 strings and was interpreted in a wrong way.

Compare correct file names for volume detach operation
**What this PR does / why we need it**:
Current volume detach code compares volume path with disk path, as it is. This PR removes '.vmdk' extension from both paths and then compares them. This makes sure that correct comparison is done irrespective of a missing '.vmdk' extension from one of the paths.
**Which issue(s) this PR fixes**:
Fixes https://github.com/vmware/kubernetes/issues/392
**Special notes for your reviewer**:
Deployed cluster on vSphere and provisioned a static volume. Verified that a statically provisioned volume gets detached even when volume path didn't contain any .vmdk extension and disk path had .vmdk extension.
**Release note**:
```vSphere cloud provider: Fix detach operation for volumes, when .vmdk extension is not specified in volume path.```
