vdo: lvm_import_vdo enhancements
Work also with devices that may have ':' inside their generated /dev/disk/by-id Ensure there is no race with systems' auto activation while using the snapshot for conversion. Update system's vdoconf.yml after the use of snapshot for conversion. Skip unnecesary prompt for 'convert' while using snapshot and query only for final snaphot merge. Prohibit conversion for a device with the PV header. Enhance 'trap' protection for more signals. Improve clean() recovery path. Replace bash 'test' command with []. Correct some output message to print $TOOL. Support also options without '-' in the middle i.e. --nosnapshot. For shellcheck predefine all variables extracted from vdoconf.yml.
