Conditional turn restriction support (#3841)

* optionally include condition and via node coords in InputRestrictionContainer

* only write conditionals to disk, custom serialization for restrictions

* conditional turn lookup, reuse timezone validation from
extract-conditionals

* adapt updater to use coordinates/osm ids, remove internal to external map

* add utc time now parameter to contraction

* only compile timezone code where libshp is found, adapt test running

* slight refactor, more tests

* catch invalid via nodes in restriction parsing, set default cucumber
origin to guinée

* add another run to test mld routed paths

* cosmetic review changes

* Simplify Timezoner for windows build

* Split declaration and parsing parts for opening hours

* adjust conditional tests to run without shapefiles

* always include parse conditionals option

* Adjust travis timeout

* Added dummy TZ shapefile with test timezone polygons

* [skip ci] update changelog
