Code Issues Proposed changes

Fix hbsAgent mgmnt interface name corruption 

The hbsAgent socket initialization process is declaring
a local string variable and then loading the management
interface name into it and setting its static management
interface config pointer to that variable.

So, when that local variable falls out of scope and that
local (stack) variable memory is recycled and changed by
its new owner then the data the management interface config
pointer points to changes and that leads to the reported
error condition and log flooding.

This update allocates a new memory pointer instead.
