Elytron aggregate-http-server-mechanism-factory includes attribute named http-server-factories which refers org.wildfly.security.http-server-mechanism-factory capability. Name of this attribute should be changed from http-server-factories to http-server-mechanism-factories because:

• it should be consistent with other Elytron resources which uses name http-server-mechanism-factory
• it can be confused since http-server-factories seems as it may also refer some org.wildfly.security.http-authentication-factory
