CreateInfoDetail create DockerInfoDetail with docker.Container Container property used in this function : HostsPath, Config.Hostname, Name, Config.Image, Config.Env, Mounts 

ContainerInfo.GraphDriver.Data["UpperDir"] Config.Labels

func (*DockerCenter) GetAllAcceptedInfo 

func (dc *DockerCenter) GetAllAcceptedInfo(
	includeLabel map[string]string,
	excludeLabel map[string]string,
	includeLabelRegex map[string]*regexp.Regexp,
	excludeLabelRegex map[string]*regexp.Regexp,
	includeEnv map[string]string,

	includeEnvRegex map[string]*regexp.Regexp,
	excludeEnvRegex map[string]*regexp.Regexp,
	k8sFilter *K8SFilter,
) map[string]*DockerInfoDetail

GetAllAcceptedInfo gathers all info of containers that match the input parameters. Two conditions (&&) for matched container: 1. has a label in @includeLabel and don't have any label in @excludeLabel. 2. has a env in @includeEnv and don't have any env in @excludeEnv. If the input parameters is empty, then all containers are matched. It returns a map contains docker container info.

func (*DockerCenter) GetAllAcceptedInfoV2

GetAllAcceptedInfoV2 works like GetAllAcceptedInfo, but uses less CPU. It reduces CPU cost by using full list and match list to find containers that 

 need to be check.

  deleted = fullList - containerMap
  newList = containerMap - fullList
  matchList -= deleted + filter(newList)
	 return len(deleted), len(filter(newList))

@param fullList [in,out]: all containers. @param matchList [in,out]: all matched containers.

It returns two integers: the number of new matched containers 

and deleted containers.
