Addition of distance constraints between user's geolocation and feature selected for mapping

[manjitapandey]

Is your feature request related to a problem? Please describe.
Currently, user can select the feature far away from their current location. This causes enumerators to share incorrect data sometimes.

Describe the solution you'd like
Restrict the user to select the feature that are far away from their current location. For that we need to necessarily ask for geolocation on mapper's page and if users click on feature far away and click on map on odk. The error message saying the feature you are trying to map is xx km away from your current location.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

As you mentioned in duplicate issue,

Instead open a confirmation dialog / modal: 'The created geometry is far away from your current location. Are you sure you wish to proceed?'

Are you suggesting just the warning message or complete blocking to submission?

Showing the warning is good but I think we should make the feature a bit dynamic my adding the feature of whether project creator wants to add restriction or not.
During project creation, we can ask project creator if they want to restrict the selection of feature away from their current location. If project creator ticks on the restriction, they can add their own proximity distance as well.
We can cover more use cases this way for both open projects and strictly monitored projects.
