docker engine-api library is deprecated(2071)

[rsingh2411]

I have made the changes in code and test file and all tests are also passed
go test -v *.go === RUN TestDockerGatherContainerStats --- PASS: TestDockerGatherContainerStats (0.00s) === RUN TestDockerGatherInfo --- PASS: TestDockerGatherInfo (0.00s) PASS ok command-line-arguments 0.008s

After adding my changes following error was coming go install -ldflags \ "-X main.version=dev-49-gc8cc01b -X main.commit=c8cc01b -X main.branch=master" ./... github.com/influxdata/telegraf/plugins/inputs/docker plugins/inputs/docker/docker.go:103: cannot use c (type *client.Client) as type DockerClient in assignment: *client.Client does not implement DockerClient (wrong type for ContainerList method) have ContainerList("github.com/docker/docker/vendor/golang.org/x/net/context".Context, types.ContainerListOptions) ([]types.Container, error) want ContainerList("golang.org/x/net/context".Context, types.ContainerListOptions) ([]types.Container, error) make: *** [build] Error 2

This was because somewhere in code the vendor context was being referred and telegraf refers the vendor context in the first place. I renamed the folder, after wards make ran succesfully. I am new to go, couldn't get solution for that.

thanks for the effort, but you'll need to make sure the project builds and all unit tests pass before submitting a PR
