[build] Create extension for WildFly 10

[SergeyLee]

What I have done:

• copied /build/as7 folder into /build/as10 and fixed strings and folders from as7 to as10
• fixed dependencies: org.wildfly (10.0.0.Final) and org.wildfly.core (2.0.10.Final)
• fixed dependency: org.jboss.jboss-vfs (3.2.11.Final)
• temporary commented dependency: org.wildfly.core.wildfly-subsystem-test (2.0.10.Final is absent in repo) and removed SleeSubsystemTestCase from ../as10/extension/src/test
• then I had problem with org.jboss.common-core module and I added it to WildFly in /modules (2.5.0.Final version)

standard-components DU deploys fine. But I have problem with deploying SimpleSlee3 application:
