Anonymous incore client

[longshuicy]

1. Allow empty or anonymous incore client
2. Remove any interaction with remote services
3. Double check if all analyses and utility functions still run
4. Check its impact on pyincore-viz

[longshuicy]

We still have at least a few place that talks to the remote service to get the demand units and demand types. Anywhere that uses def get_allowed_demands(self, hazard_type, timeout=(30, 600), **kwargs)

Analysis being affected by are:
pipelinedamage.py
buildingdamage.py
nonstructbuildingdamage.py

This is resolved

Some of the pyincore-viz method assumes wms layer on geoserver. Need to find out what they are and what's the implication
