voltctl: ambigous binaries available

This problem might be fun to deal with:

VOLTHA job setup normally iwll install a voltctl binary for use.

On the community pod  node I found a copy in the system directory: /usr/local/bin.

The commands are different versions.

This setup will be problematic for jobs, any v2.8, v2.9 ... jobs will have potential to use wrong command version if they rely on a default searchpath.

VOLTHA binaries in /usr/local/bin should be removed to  make this problem clear.

Unsure how much fallout this might cause, if VOLTHA jobs depend on the binary by default it could cause mass job failures.  This should be revisited after the release.
