Avoid ticket mark as client updated when ticket been created (attachment, ConnectWise)

[Nness]

Lately, server had change, where upload attachment will mark ticket as client updated.

This is good if client only uploaded attachment, but it also cause new ticket with attachment to fall under this category.

• [x] Add query parameter to attachment API, allow front end application to describe its intention.
• [x] Default behaviour is not flag Client Updated to true.
• [x] Portal's ticket detail interface's add attachment should specify it's intention, where create ticket shouldn't.

Above fix will make sure existing and old portal will have default behaviour they had before. Then additional portal side change could help with client upload attachment scenario.

@DDAndyChen could you work on first and second task at server side, make sure it is shipped with this week's server release?

I will add query parameter support to portal later.
