Weirdly, the existence of /sys/fs/resctrl/info/MB does not always mean
that MBA is available and used on the system. Instead of assuming that
copy the values from the default (root) allocation. This also makes it
nicer to use the proper values in case the system does not use
percentages or when the root allocation already limits the bandwidth.

Add new XML section to report host's memory bandwidth allocation
capability. The format as below example:
<host>
.....
<memory_bandwidth>
<node id='0' cpus='0-19'>
<control granularity='10' min ='10' maxAllocs='8'/>
</node>
</memory_bandwidth>
</host>
granularity ---- granularity of memory bandwidth, unit percentage.
min ---- minimum memory bandwidth allowed, unit percentage.
maxAllocs ---- maximum memory bandwidth allocation group supported.

This test initializes capabilities from vircaps2xmldata (since it exists there
already) and then requests list of free bitmaps (all unallocated space) from
virresctrl.c
Desirable outputs are saved in virresctrldata.
