Add SwitchYard dependencies to IP BOM

A few notes:

1) These are additions only - no changes to existing dependencies.
2) Note that the current version of Netty being used in the IP BOM (3.2.6) does not match EAP (3.6.2). The groupId changed between the two (org.jboss.netty -> io.netty), so I have simply added a new version property and the new dependency definition for Netty 3.6.2.
3) The red lines in the diff are not changes to dependencies; a few existing dependencies were out of alphabetical order so I re-ordered them when our dependencies were added.
