This fixes the following error when trying to upgrade:
```
cannot change name of input parameter "organization_name"
```
The problem was introduced ages ago. I fixed it by running a script:
```bash
BAD_REGEXP='CREATE OR REPLACE FUNCTION cdb_dataservices_client\._cdb_geocode_admin0_polygon (username text, orgname text, country_name text)'
REPLACEMENT='CREATE OR REPLACE FUNCTION cdb_dataservices_client._cdb_geocode_admin0_polygon (username text, organization_name text, country_name text)'
git grep -l "$BAD_REGEXP" | xargs sed -i "s/$BAD_REGEXP/$REPLACEMENT/g"
```
Add config function in postgres explicitly to get MapzenGeocoderConfig.
Bump versions for client and server APIs. New MapzenGeocoderConfig
included to be able to use current QuotaServices with non-configured
users.
Add routing with waypoints functions to client and server. Includes
signature checks tests for the Postgresql functions and unit and
integration tests for the Python library.
Add client v0.6.0 and server v0.9.0
