New subject: [libvirt PATCH 1/5] qemu: Probe for a few params supported by migrate-set-parameters
These parameters were originally set via dedicated commands which are
now deprecated. We want to use migrate-set-parameters instead if
possible.

Since QEMU_CAPS_MIGRATION_PARAM_CACHE_SIZE is relevant to XBZRLE only,

'xbzrle-cache-size' the XBZRLE part should be also part of the
capability and it's status XML string.

provided that you add 'XBZRLE' to QEMU_CAPS_MIGRATION_PARAM_CACHE_SIZE
and it's status XML string.
