show vsphere-cloud-controller-manager version in the log correctly

[nicolehanjing]

What this PR does / why we need it:
vsphere-cloud-controller-manager version is shown as ${VERSION} in the log:

I1201 10:00:32.996286       1 main.go:81] vsphere-cloud-controller-manager version: ${VERSION}

we should see a version number instead of ${VERSION}.

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #533

Special notes for your reviewer:
verified the fix:

I1203 00:09:19.942725       1 main.go:81] vsphere-cloud-controller-manager version: 1.22.3

I think this fix is a good start, but shouldn't the fix be passing the version into the Docker build command as a build arg instead of hard coding it?

I think either works - using the fixed value and updating it when we have a new version released; or fetch the version value via git commands
I think using a fixed value can help to prevent possible issues in some other environments, and I'm planning to add this in my WIP release doc to inform the maintainer to update the version value when a new release version is available.

pass version info dynamically when building docker image

[nicolehanjing]

for local development, if you run docker build command without version info, the log is still not correct. Probably we can leave the fixed value and update it when we have a new release version
