MULE-7203: Move ws-proxy from patterns/core into a new web services module

Created mule-module-ws. Moved WSProxy and ws namespace from pattern-core to mule-module-ws. Made pattern-core depend on mule-module-ws so as to keep existing pattern:web-service-proxy element working (using the implementation in mule-module-ws). Moved HttpProxy to mule-transport-http and made mule-module-ws depend on mule-transport-http as WSProxy depends on HttpProxy.
MULE-7203: Move ws-proxy from patterns/core into a new web services module

Added mule-module-ws to the embedded distribution
increasing surefire memory
MULE-6889: Adding test to verify behaviour
MULE-7140 - adding configuration to maven-resources-plugin to include empty directories in the distro
Initial import of work on Web Service Consumer
MULE-7140 - Adding file inside domains folder in distributions so it gets versioned by git. Removing that file from distributions using assembly.xml. Reverting maven-resources-plugin configuration since it is no longer necessary
MULE-7198: Build fails due to error downloading dependencies of jBPM module. Fixed repository location since it was moved.
MULE-6926: Ignoring flacky test
MULE-6367: FTP Inbound endpoint fails when reading empty file. Added functional test case. Removed explicit check for empty files.
MULE-6926 - Ignore flaky tests QuartzReceiveAndDispatchJobTestCase
MULE-7223 - Change flow processing phase to call exception strategy if there is an exception sending inbound endpoint response message
MULE-7217	Migrate Tests to new Web Services Consumer module

Added some basic tests to the web services consumer.
MULE-7223 - applying changes after code review - renaming misleading variable name - extracting method for getting the right exception to create the failure response
MULE-7218: Get SOAP action working correctly

Changed WSConsumer so that the SOAP action is read from the WSDL.
MULE-7207: Implementing Scatter-Gather router for parallel broadcast

MULE-7222: An exception to be thrown when a SOAPFault is returned

Added an interceptor to catch CXF exceptions thrown on SOAP faults and wrapping then into a custom SoapFaultException from the ws consumer module.
