Issue 7488 docker labels (#7770)

Improve the metadata detection for containers. The system_info structure has been updated to hold separate copies of OS_NAME, OS_ID, OS_ID_LIKE, OS_VERSION, OS_VERSION_ID and OS_DETECTION for both the container environment and the host. This new information is communicated through the /api/v1/info endpoint. For the streaming interface a partial copy of the info is carried until the stream protocol is upgraded. The anonymous_statistics script has been updated to carry the new data to Google Analytics. Some minor improvements have been made to OS-X / FreeBSD detection, and the detection of virtualization. The docs have been updated to explain how to pass the host environment to the docker container running Netdata.
