migration: Introduce capability 'x-colo' to migration
We add helper function colo_supported() to indicate whether
colo is supported or not, with which we use to control whether or not
showing 'x-colo' string to users, they can use qmp command
'query-migrate-capabilities' or hmp command 'info migrate_capabilities'
to learn if colo is supported.
The default value for COLO (COarse-Grain LOck Stepping) is disabled.
