Pipe raw CLI output for commands without RPC equiv

[mirceaulinic]

As per our discussion in the forums, I am going to add the facility to pipe the output.

For some obscure reasons, although the device returns all these details (or at lease this is what logs show), ncclient does not receive that.

Logs from device:

Which is almost the same, just that the pipe tag is not there:

Oct 21 00:23:29 [1709] Outgoing: <pipe>
Oct 21 00:23:29 [1709] Outgoing: <more-match-string>
Oct 21 00:23:29 [1709] Outgoing: napalm
Oct 21 00:23:29 [1709] Outgoing: </more-match-string>
Oct 21 00:23:29 [1709] Outgoing: </pipe>

That's not such a big issue, as anyway we have this info and we'll probably need to handle the filtering based on the input request.

Any thoughts on this?
