Change request and conflicts

When the initial state of a Change request has changed (i.e.: you want to modify a Directive, but someone else changes about that Directive has been accepted before yours), your change can’t be validated anymore.

For now, we decided to reduce to the possibility of an error or inconsistency when there are concurrent changes. In a future version of Rudder, there will be a system to handle those conflicts, and make sure actual changes are not overwritten.
