kube: Add support for podman pod logs
Following PR adds support for `kubectl` like `pod logs` to podman. Usage `podman pod logs <podIDorName` gives a stream of logs for all the containers within the pod with **containername** as a field. Just like **`kubectl`** also supports `podman pod logs -c ctrIDorName podIDorName` to limit the log stream to any of the specificied container which belongs to pod.

+## NAME
+podman\-pod\-logs - Displays logs for pod with one or more containers
+
+## SYNOPSIS
+**podman pod logs** [*options*] *pod*
+
+## DESCRIPTION
+The podman pod logs command batch-retrieves whatever logs are present with all the containers of a pod. Pod logs can be filtered by container name or id using flag **-c** or **--container** if needed.
+
+Note: Long running command of `podman pod log` with a `-f` or `--follow` needs to be reinvoked if new container is added to the pod dynamically otherwise logs of newly added containers would not be visible in log stream.
+
+## OPTIONS
+
+#### **--container**, **-c**
+
+By default `podman pod logs` retrives logs for all the containers available within the pod differentiate by field `container`. However there are use-cases where user would want to limit the log stream only to a particular container of a pod for such cases `-c` can be used like `podman pod logs -c ctrNameorID podname`.
+
+#### **--follow**, **-f**
+
+Follow log output. Default is false.
+
+Note: If you are following a pod which is removed `podman pod rm`, then there is a
+chance the the log file will be removed before `podman pod logs` reads the final content.
+
+#### **--latest**, **-l**
+
+Instead of providing the pod name or id, get logs of the last created pod. (This option is not available with the remote Podman client)
+
+#### **--since**=*TIMESTAMP*
+
+Show logs since TIMESTAMP. The --since option can be Unix timestamps, date formatted timestamps, or Go duration
+strings (e.g. 10m, 1h30m) computed relative to the client machine's time. Supported formats for date formatted
+time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
+and 2006-01-02.
+
+#### **--until**=*TIMESTAMP*
+
+Show logs until TIMESTAMP. The --until option can be Unix timestamps, date formatted timestamps, or Go duration
+strings (e.g. 10m, 1h30m) computed relative to the client machine's time. Supported formats for date formatted
+time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
+and 2006-01-02.
+
+
+#### **--tail**=*LINES*
+
+Output the specified number of LINES at the end of the logs. LINES must be an integer. Defaults to -1,
+which prints all lines
+
+#### **--timestamps**, **-t**
+
+Show timestamps in the log outputs. The default is false
+
+## EXAMPLE
+
+To view a pod's logs:
+```
+podman pod logs -t podIdorName
+```
+
+To view logs of a specific container on the pod
+```
+podman pod logs -c ctrIdOrName podIdOrName
+```
+
+To view all pod logs:
+```
+podman pod logs -t --since 0 myserver-pod-1
+```
+
+To view a pod's logs since a certain time:
+```
+podman pod logs -t --since 2017-08-07T10:10:09.055837383-04:00 myserver-pod-1
+```
+
+To view a pod's logs generated in the last 10 minutes:
+```
+podman pod logs --since 10m myserver-pod-1
+```
+
+To view a pod's logs until 30 minutes ago:
+```
+podman pod logs --until 30m myserver-pod-1
+```
