The target= setting in xl disk configuration can be used to encode
meta info that is meaningful to a backend. Leverage this fact to
support qdisk network disk types such as rbd. E.g. <disk> config
such as
<disk type='network' device='disk'>
<driver name='qemu' type='raw'/>
<source protocol='rbd' name='pool/image'>
<host name='mon1.example.org' port='6321'/>
<host name='mon2.example.org' port='6322'/>
<host name='mon3.example.org' port='6322'/>
</source>
<target dev='hdb' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
</disk>
can be converted to the following xl config (and vice versa)
disk = [ "format=raw,vdev=hdb,access=rw,backendtype=qdisk,
target=rbd:pool/image:auth_supported=none:mon_host=mon1.example.org\\:6321\\;mon2.example.org\\:6322\\;mon3.example.org\\:6322"
]
Note that in xl disk config, a literal backslash in target= must
be escaped with a backslash. Conversion of <auth> config is not
handled in this patch, but can be done in a follow-up patch.
Also add a test for the conversions.
