HPCC-11698 WARNING: Remote file connect Too many open files

Roxie was leaving sockets open for remote files that it has checked the

be in use...)

HPCC-11760 Fix getTargetClusterInfo() in workunit.cpp

The getTopologyCluster() changed recently to not return the 'conn'
for environment data. The getTargetClusterInfo() and another
