3f2a7810cf Respect non-enforced constraints when editing/adding features 
Warnings are shown, but features can be committed. Fields which
fail an unenforced constraint are now shaded in yellow to differentiate
from the red failure for enforced constraints.

fac5bc0691 [FEATURE] Field constraints can be enforced or not 
Non-enforced constraints just show a warning to the user, but
do not prevent committing the feature. Enforced constraints
block users from comitting non compliant features.

Any constraints detected by the provider are always
enforced.

a6319a47d7 If the layer is NOT being edited then only check layer based constraints 
and not any constraints enforced by the provider

Because:

1. we want to keep browsing features nice and responsive. It's nice to give
 feedback as to whether the value checks out, but not if it's too slow to
 do so. Some constraints (eg unique) can be expensive to test. A user can
 freely remove a layer-based constraint if it proves to be too slow to
 test, but they are unlikely to have any control over provider-side
 constraints

2. the provider has already accepted the value, so presumably it doesn't
 violate the constraint and there's no point rechecking!

f6c1bf7f5b Add gui for setting/exposing constraints in field properties 
Provider set constraints cannot be changed by users, ie
if a not null constraint is set on the field at the database
then QGIS users cannot clear this constraint.
