Because the SSH exec functions do not currently support execution with
input, some users (such as the podman-image-scp) must operate in two
phases, first copying a file to the remote host, and then executing a
command with shell redirection and removing the temporary file.
This API extension allows those users to simplify their code and
avoid the use of temporary files.

Used `go fmt` rules to migrate away from deprecated functions, for
instance `gofmt -w -s -r 'ioutil.TempDir(a, b) -> os.MkdirTemp(a, b)'`

initial implementation of the ssh package including:
- nativeConnectionCreate() / golangConnectionCreate()
- n/a / golangConnectionDial()
- nativeConnectionScp() / golangConnectionScp()
- nativeConnectionExec() / golangConnectionExeC()
the way this works, is there are publicly accessible functions Create, Exec, Dial and Scp. podman will have a new global flag --ssh` that will allow users to choose native or golang based ssh functions. The functionality in containers/common (here) also checks if you have the necessary binaries installed
