Add marker clustering to map

[joshas]

There are too many markers on screen, use marker clustering, e.g. https://developers.google.com/maps/documentation/android-api/utility/marker-clustering .

Thank you, @joshas for the idea!

We discussed this issue in our team and decided to not add clustering, because they do not give a clear picture of the density of the problems in a particular area of the city. We will add filters to map view later, which will let the user see only the types of reports he is interested in.

A bunch of overlapping markers will not provide a clear picture of density of the problems, you'll need to draw a heatmap for that ( https://developers.google.com/maps/documentation/android-api/utility/heatmap ).
Looking forward to map filters.

Thank you for the ideas. We will take this into consideration when planning new features.
