upgrade: drop support for old style optimization names

Old style optimization names like `redeltaparent` were converted into
`re-delta-parent` more than two years ago. The old names were kept around for
sometime because of BC reasons.

Refer 5608b5a6c3231c4ec771171cc3079142c7672be6. The commit states the map is
there for a while and we can drop them as the underlying command is a debug
command.
