ssh-console: only enable keepalive option
There was some further discussion on dc0eec8 after it was merged. The
consensus was that it may have gone a bit too far on client connection
restrictions. For example, why add the -I to disconnect a fully working
(but idle) session?
It was also clarified that the -K option enables a keepalive message
every X seconds. The client is disconnected after 3 keepalive timeouts.
Given this, it was agreed to reduce the value from 10 to 5 to give the
client a total of 15 seconds to keep a connection alive.
Tested:
- Loaded on a p10bmc system, connected multiple clients to 2200 and
2201 and caused extensive traffic in both. No issues found.
