Error in training material.

Hi. It seems I found an error in training material.

I believe error is here:

APIS AND ACCESS – APIs and Access – Additional Resource Methods

GET /api/v1/namespaces/{namespace}/pods/{name}/exec

1) There have to be POST and not GET for exec command;
2) It seems it is impossible to get response using curl, because it doesn’t support SPDY 3.1 protocol.
