HPCC-10156 Add WsTopology method ListTargetClusters

The existing TpTargetClusterQuery returns too much information and
can be slow. A new method is requested which only returns cluster name,
type, and whether the cluster is a 'default' target (for jobs like
syntax check, etc) or not. The method is implemented by this fix.

The default target cluster may be specified in esp.xml (see the other
subtask in the parent issue). If not, the isDefault will be set using
the following logic: Loop through all targets. If an hthor is found,
it will be the 'default'. If no hthor, the first thor cluster will be
the 'default'. If no hther and no thor, the first roxie cluster will
be the 'default'.
HPCC-10015 Add WUID wildcard search for WUQuery

This fix implements WUID wildcard search for WUQuery. A user
may input W20130918* as a search request and WUQuery returns
a list of WUs that were created on that day.

HPCC-9521 Refactor CDfsLogicalFileName to make it purely representational of a logical file, avoid it resolving/looking up

Currently CDfsLogicalFileName resolves any wildcards in logical file names
when it is instantiated. This is unnecessary since in most cases they dont
need to be. This pull request delays the expansion until it is actually
needed, by adding a new "isWild" and "expand" method to the interface.

HPCC-10183 ECL Record Layout metadata is not reported for XML files in hthor

HThor is currently not writing the ECL record layout for XML files. This
fix checks to see if that information is available and if so, writes it
along with the other file properties
