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.

On some platforms the number of bits in the cbm_mask might not be
divisible by 4 (and not even by 2), so we need to properly count the
bits. Similar file, min_cbm_bits, is properly parsed and used, but if
the number is greater than one, we lose the information about
granularity when reporting the data in capabilities. For that matter
always report granularity, but if it is not the same as the minimum,
add that information in there as well.

Add info from yet another machine, this time with resctrl data so that
we can extend tests easily in a test-driven way.
