test/api: move govc installation to common/vsphere.sh

Move the installation of the VSphere client out of the
`api/common/aws.sh` `installClient()` function into a dedicated
`installClientVSphere()` function in `api/common/vsphere.sh`.

Rename the `installClient()` in `api/common/aws.sh` to
`installAWSClient()`. Introduce `installClient()` in both,
`api/aws.sh` and `api/aws.s3.sh`, which calls `installAWSClient()`.

Call `installClientVSphere()` conditionally when testing VMDK image type
in `api/aws.s3.sh` and `api/generic.s3.sh`.
