Check Qcow2 version before using --bitmaps

[JoaoJandre]

Description

This PR adds a validation on the volume copy process. Before adding the --bitmaps flag to the convert command, a check is made in the volume to guarantee that the volume is at least version 3; if it is not, the flag is not added.

How Has This Been Tested?

Upload image with old compat version, e.g. http://dl.openvm.eu/cloudstack/macchinina/x86_64/macchinina-kvm.qcow2.bz2, attach to VM, stop VM, migrate volume.

Before:

Failed to convert [/mnt/b59eff0f-5b97-37ed-a513-9e1983d1d19b/2784ec51-4776-4b03-9a85-198c465e7d25] to [/mnt/a66f48f5-13c6-3676-b320-a15d32bbf32f/2784ec51-4776-4b03-9a85-198c465e7d25] due to: [qemu-img: Source lacks bitmap support]. org.apache.cloudstack.utils.qemu.QemuImgException: qemu-img: Source lacks bitmap support

After:
Image is converted successfully as the --bitmaps option is not informed.

test_create_pvlan_network Error 0.11 test_pvlan.py

Looking at the logs, three of them seem network related. While I don't understand the failure on test_18_retrieve_cpvm_single_file; it seems like an issue with the test itself (the command returned a URL but it was not what the test was expecting). In any case, none of the failures seem to be caused by this change.
