HO: vty: rename ho decision 1 vty to 'handover1' with 'handover' alias 

Handover decision 2 arguments are now configured by 'handover2 foo'. To match
that scheme, rename the previously 'handover foo' args for handover decision 1
to 'handover1 foo'.

For backwards compatibility, still provide aliases of the original VTY
commands. Writing back the config will result in 'handover1' though.
