Improve Performance django-jsonattrs

[wonderchook]

Tasks need to be outlined at the beginning of the sprint.

A couple of examples where this issue is causing a low performance (thanks to @amplifi for checking the logs!).

In platform:

• Lagos project: either loading the overview page or accessing to a specific location.

Overview (around 4 seconds to load):
https://platform.cadasta.org/organizations/jei/projects/lagos-tenure-assessment-1/
One location (around 8 seconds to load one location):
https://platform.cadasta.org/organizations/jei/projects/lagos-tenure-assessment-1/records/locations/ccykz2hmrn26a3s9vd4gnjkc/

• Telangana:

Overview (around 5 secs to load):
https://platform.cadasta.org/organizations/landesa/projects/telangana-survey/

One location (around 9 secs to load):
https://platform.cadasta.org/organizations/landesa/projects/telangana-survey/records/locations/ay64rs2an99qua9xbz94xbc8/

In staging behaviour is similar.

@oliverroick What do you think about closing this for now?

[oliverroick]

Yes, closing this for the time being. We should address front-end performance next
