Maintenance not messaging over cluster-host network

[Eric MacDonald]

Maintenance is not resolving the cluster-host ip addresses properly for both the mtcAgent and mtcClient processes. The cluster-host network is used as a messaging backup path between controller and subordinate hosts under a number of failure modes.

Severity: Minor - only corner case failure mode handling is affected.

Steps to Reproduce:
-------------------
Provision a system with a cluster-host network. mtcClient should be sending periodic mtcAlive messages to the active controller over both management and cluster-host networks.

Expected Behavior
------------------
computes send mtcAlive messages to active controller over a provisioned cluster-host network.

Actual Behavior
---------------
No periodic mtcAlive messages are received on the active controller cluster-host network.

Reproducibility
---------------
Reproducible

System Configuration
--------------------
System with provisioned cluster-host network.

Branch/Pull Time/Commit
-----------------------
All since rename of infra to cluster-host network.

Last Pass
---------
This hasn't worked since the cluster network was introduced

Timestamp/Logs
--------------
Not required. Issue is missing messages not error logs.

Marking as stx.2.0 gating as this impacts fault detection/handling of the cluster network interface
