DockerInfo - Comand /usr/bin/docker info
This parser reads the output of /usr/bin/docker info
.
The resulting data structure is avaible in the data
member of the class
and takes the form of a dictionary whose keys are the “keys” in the output
(the string before the :
) and whose values are the values (the string
following the :
), all stripped of leading and trailing spaces.

Examples
>>> docker_info = shared[DockerInfo]
>>> docker_info.data['Containers']
'0'
>>> docker_info.data['ID']
'QPOX:46K6:RZK5:GPBT:DEUD:QM6H:5LRE:R63D:42DI:4BH3:6ZOZ:5EUM'
If the command does not return the information (for example, the Docker
daemon isn’t running, the data
dictionary is empty.
