bluesky user PKI issue on some 10.13 clients

[sphen13]

To add more diagnostic information we can maybe report better in the bluesky admin interface as to why the "tunnel is down"

This patch changes to language in the web-portal from:

ERROR: no tunnel established

to:

ERROR: tunnel issue TO client

This would indicate that there is an issue with the PKI negotiation from the server to the client. The tunnel is in fact up. We will not trigger a restart of the tunnel on the client.

or

ERROR: tunnel issue FROM client

This would indicate that the tunnel is down and cannot be established from the client to the server. Normal methods of fixing (re-key etc) will take place.

thoughts @bestmacs ?

Too early to say, but #36 fixes my broken clients so far.
