MOB-651: Decouple File Servers from Config Service and Authenticators

- Minor JLAN changes (backward compatible)
   - CIFSAuthenticator implements an interface (to allow dynamic proxying to authentication subsystem)
   - CIFSAuthenticator accesses ServerConfiguration via ServerConfigurationAccessor interface and doesn't retain references to config sections (again to allow dynamic proxying and hot swapping)
   - ConfigSections have way of directly setting container initialised authenticators, sharemappers, etc.
   - Authenticators, etc. still support initialisation from config service in backward compatible manner.
- Most of ServerConfigurationBean moved to AbstractServerConfigurationBean superclass.
- New org.alfresco.filesys.config package with ServerConfigurationBean implementation and supporting classes that can be initialised by a Spring container.
- File server authenticators moved into authentication subsystem. TODO: Kerberos and NTLM
