Subject: Rename the OpMigrate* parameter 'live' to 'mode'
X-Git-Tag: v2.2.0rc0~46
X-Git-Url: https://code.grnet.gr/git/ganeti-local/commitdiff_plain/8c35561fed3ec474eccc5a6f03ada797d13b109b

Rename the OpMigrate* parameter 'live' to 'mode'

This is needed as now the parameter is no longer boolean, but tri-state.
