SSH Monitor causing Failed to receive KEXINIT msg ons ASR 9Ks

Description

Current implementation of org.opennms.netmgt.poller.monitors.SshMonitor results in excessive logging on Cisco ASR 9ks. The following syslog gets generated everytime:

RP/0/RSP0/CPU0:Jun 14 15:21:44.466 : SSHD_[65604]: %SECURITY-SSHD-6-INFO_GENERAL : Client closes socket connection
RP/0/RSP0/CPU0:Jun 14 15:21:44.469 : SSHD_[65604]: %SECURITY-SSHD-3-ERR_GENERAL : Failed to receive KEXINIT msg from client

This excessive logging is causing our Network Operations to no longer allow SSH from our OpenNMS servers.
