Execute a command in a container.

Examples:
 # Get output from running the 'date' command from pod mypod, using the first container by default
 kubectl exec mypod -- date

 # Get output from running the 'date' command in ruby-container from pod mypod
 kubectl exec mypod -c ruby-container -- date

 # Switch to raw terminal mode; sends stdin to 'bash' in ruby-container from pod mypod
 # and sends stdout/stderr from 'bash' back to the client
 kubectl exec mypod -c ruby-container -i -t -- bash -il

 # List contents of /usr from the first container of pod mypod and sort by modification time
 # If the command you want to execute in the pod has any flags in common (e.g. -i),
 # you must use two dashes (--) to separate your command's flags/arguments
 # Also note, do not surround your command and its flags/arguments with quotes
 # unless that is how you would execute it normally (i.e., do ls -t /usr, not "ls -t /usr")
 kubectl exec mypod -i -t -- ls -t /usr

 # Get output from running 'date' command from the first pod of the deployment mydeployment, using the first container by default
 kubectl exec deploy/mydeployment -- date

 # Get output from running 'date' command from the first pod of the service myservice, using the first container by default
 kubectl exec svc/myservice -- date
