Remove surface command

[perrygeo]

Surface tests are failing. Worth considering if we should bother fixing this as the API is deprecated and slated to be removed soon anyways.

What you've tried already

pytest tests/test_surface.py

Expected outcome

tests pass

Actual outcome

The URL expected by the responses mock is something like

https://api.mapbox.com/v4/surface/mapbox.mapbox-terrain-v1.json?access_token=bogus
&layer=contour&fields=ele&geojson=true&interpolate=true&zoom=14
&points=-112.084004%2C36.05322%3B-112.083914%2C36.053573%3B-112.083965%2C36.053845

but the URL constructed by the SDK is slightly different in order and rounding of coordinates:

https://api.mapbox.com/v4/surface/mapbox.mapbox-terrain-v1.json?access_token=bogus
&points=-112.084004%2C36.053220%3B-112.083914%2C36.053573%3B-112.083965%2C36.053845
&geojson=true&fields=ele&layer=contour&zoom=14&interpolate=true

[perrygeo]

Given that the Surface API is deprecated, we should avoid putting any effort into these tests and instead remove mapbox surface in the next release.

Changing title to reflect the new scope.
