add tentative support for geofabrik extracts (breaks on multiple files)
make osm dir always
replace osm2pgsql with imposm3 for more consistent processing
cln: be consistent with no whitespace in ansible {{variables}}
move imposm build to start, so don't have to jank around with postgres service
also, less likely to run into mem issues
cln: rm empty vars statement
only try to build imposm3 if it doesn't already exist
read VM settings from variables.yml: amount of RAM and number of CPUs
use /var/osm/cache for the imposm3 cache dir so it persists on restarts
make the PostGIS port configurable in variables.yml
this is the port that forwarded on the host machine
Update README to note the simpler way of changing the port number
rm unused vagrant.yml file
cln: clarify comment in bootstrap script
import data into public schema by default
add geofabrik extracts to README intro sentence
fix: only run download task when geofabrik extracts are defined
