Deprecate "duration" kind

[kwk]

A duration in Go is nothing but an int64:

“A Duration represents the elapsed time between two instants as an int64 nanosecond count. The representation limits the largest representable duration to approximately 290 years.” (source: godoc)

We don’t have a field at the moment that uses this field kind and I cannot foresee any field that might need it.

I want to remove that field kind because it is not used and more importantly because we cannot store int64 numbers in JSONB as that only can handle IEEE-754 double precision floating point values. So we eventually will reach a point at which we do loose precision.

Approval requested from:

Please check your name if you're fine with the removal.

@bartoszmajsak I've added a checkbox list where you can toggle your name if you approve the removal.

Clear, so that's an approval process. Well... for me it's simple - YAGNI so I approve :)
