This add Envs to container spec as a metadata source. When using prometheus
exposition format, they will be merged into the list of metrics' labels.
Also changed the cli flag to docker_env_metadata_whitelist, and add refenrences
of whitelist envs to API

Remove spec-related fields from stat.
We can simplify the stats a bit further by handling Int and Float better.
But this was big enough change already.
Verified v1 and v2 spec/stats/appmetrics APIs.
First cut on 2.0 stats API. Main change in returned stats is that presence checks (eg. HasCPU) are embedded in each stat.
Added support to handle querying container with name.
Current syntax:
/stats?name=/&count=1,
/stats?name=docker/928c058ce260ac2a55972b18cb991fa0475fbbb7bc15bd295e62b76964d05fe6 [default count: 64]
Other handlers to include: dockerid, dockeralias. We can make subcontainers inclusion as an option too.
/storage returns {device, mountpoint, capacity, usage} for all filesystems.
In addition, it also detect and applies label for each filesystem - currently two - "root", "docker-images".
/storage/<label> returns info about the filesystem with specific label. eg. /storage/root returns info for root filesystem.
