[WFCORE-208] : Expose 'singleton' type information in read-children-types

If the "include-singletons" parameter is set to "true", the operation result will include the full key/value pair for any singleton registration.
If "include-singletons" is "true" a non-fully-qualified type (i.e. just key instead of key=value) will only appear in the result if there is a wildcard registration for that key.

subsystem's XML prior to validate it against a XSD schema.

JIRA: https://issues.jboss.org/browse/WFCORE-447
Add XSD validation of susbsystem's XML

add methods in AbstractSubsystemBaseTest to validate the
subsystem's XML (either from the tests or from the templates
used to build the server configuration) against a given XSD schema

Subsystems need to override getSubsystemXsdPath() and
getSubsystemTemplates() to activate the validation tests.
