… to get SAP process list from remote host

* Added option to retrieve all available files from remote SAP host to
sap_mgmt_con_getlogfiles, based on the listing request provided in
sap_mgmt_con_listlogfiles module, if the variable GETALL is set to true.
Kept previous functionality of retrieving just one chosen file.

* Added new module sap_mgmt_con_getprocesslist to remotely list SAP
processes using SAP SOAP interface. Based on the other sap_mgmt_con_*
modules by Chris John Riley.

Implemented the fixes, and re-tested the modules
