[libvirt] [PATCH v2 0/4] add disk driver metadata_cache_size option

[Nikolay Shirokovskiy]

1st docs patch may need tweaks if merged now (if -blockdev will not be
available in 4.10)

diff from v1 [1]
===============
- support only -blockdev configurations
- add 'default' value for the attribute
- set QEMU_CAPS_QCOW2_L2_CACHE_SIZE only for recent qemu versions (see 2nd patch)
- factor out API changes to distinct patch
- fix xml2argv test to blockdev configuration
- factor out xml2argv test to distinct patch as it is not yet passing
- other misc changes
