Drawing tool limit should be extended and user should be aware of the limit

Who requested this new feature?

SITN

Is your feature request related to a problem?

Yes. Drawing tool (redlining) is limited to the length of URL which is already quite full on modern geoportals with big layertrees. User is given the feedback its drawing is too big only when he wants to share the drawing. It's usually too late as he already spent hours drawing its art.

Describe the solution you'd like

Bigger limit would be nice. Maybe by saving the drawing to local storage first and then POSTing it to database when doing the shorturl? Also, user should get an alert when approaching the limit so he could save it.

Additional information or points to watch out for

Drawing lenght should not be limitless.

I think this is a very important feature. Everything in the URL is a big problem when we have many active layers and some drawings.
I think we should think of a new way to remember what as been activated in the layertree or drawn, without using the URL.

The length of the URL is also a Problem in this ticket : #12
