conf: add metadata/record_removed_entities configuration setting
The metadata/record_removed_entities is a global switch which enables or
disables recording removed entities (like dead LVs) in metadata.
If both metadata/record_removed_entities=1 lvm.conf option and
--nohistory command switch is used at the same time, the --nohistory
has higher priority.
