Description

Right now it's possible to specify flags that have no meaning unless another flag is turned up. For example:

-enable_api_security=true
-shiro_ini_path=/etc/aurora/shiro.ini
-shiro_realm_modules=org.apache.aurora.scheduler.http.api.security.Kerberos5RealmModule

does nothing and has no warning. The correct form is obviously:

-enable_api_security=true
-shiro_ini_path=/etc/aurora/shiro.ini
-shiro_realm_modules=org.apache.aurora.scheduler.http.api.security.Kerberos5RealmModule,org.apache.aurora.scheduler.http.api.security.IniShiroRealmModule

Investigate changes to our command-line framework that would get us a better error message here.
