Merge pull request #21 from oktocat/v0.11

Postinst for IPVS plugin.
Update control
Print warning if docker registry is not specified.
Add cocaine to group 'docker' in postinst script.

Cocaine isn't allowed to connect to docker's unix-socket by default. We must add user 'cocaine' to group 'docker' to allow the docker plugin to use the docker.
Swarm: Moved to swarm-0.6

Fixed all usages of libswarm. Fixed debian/control
Fix type to store resource limitations in the docker isolation.

Docker uses signed integer to store the limitations and negative values are allowed (e. g. -1 in MemorySwap). So the plugin also must allow these values.
Bump version.
Merge pull request #22 from euroelessar/v0.11

Swarm: Moved to swarm-0.6
Disabling all ZMQ stuff.
Version bump.
Throw proper exceptions from docker isolation.

Cocaine Runtime expects cocaine::error_t exceptions from all components.
Merge branch 'v0.11' of github.com:cocaine/cocaine-plugins into v0.11
Bump version.
urlfetch: it requires boost::thread, which previously was derived from swarm, where it is not used. Ubuntu precise and other modern linkers drop this deps, which doesn't allow cocaine plugin to start
v0.11.2.2
Support Docker 0.8.

It seems that response JSON on request "/containers/create" changed in docker 0.8. Before member "Warnings" was array, now it may be Null.
Bump version - 0.11.2.3.
Check if JSON object is array, if we want to use it as array.
Merge branch 'v0.11' of github.com:cocaine/cocaine-plugins into v0.11
Fix incorrect RapidJson usage in Docker plugin.

RapidJson array doesn't copy strings, which are pushed to it. Now the plugin stores all data while RapidJson object is used.
