In a 2.6.* release we will standardize Grouper utility classes

• Example classes: GrouperUtil, SubjectUtils, GrouperUtilElSafe, etc
• Make sure this assumption is valid: only Grouper admins are writing JEXLs and scripts which use utility classes
• Consolidate logic so that
  • Any utility method which can live in GrouperClientUtils has logic moved there
  • Any utility method which cannot live in GrouperClientUtils (due to class dependencies) has logic moved to GrouperUtil
  • No method signatures change (so compiled code still works).  i.e. if a method exists, deprecate and delegate to GrouperUtil or GrouperClientUtils 
  • Deprecate methods not in GrouperClientUtils and GrouperUtil.  Deprecate utility classes not GrouperClientUtils and GrouperUtil
  • GrouperUtil will inherit from GrouperClientUtils 
  • "grouperUtil" will be in any Grouper (non-client) jexl as GrouperUtil and "grouperClientUtils" will be in any client jexl by default
  • All GrouperClientUtils methods will have wrapper methods in GrouperUtil so there is one easy Javadoc to refer to
• The first part of a util method name should organize the namespace, e.g. "batch" in "batchNumberOfBatches()" is for batching methods, "ldap" in "ldapEscapeRdn()" is for ldap methods, etc
