APIs should use data from new pipeline

fixes #188

modified APIs to handle the new data schema, mostly search API
pipelines content_html is converted to content_text - currently it only converts br html elements to new lines
/geo/places and linkify apis were modified to use elasticsearch
elasticsearch index creation was modified to match the new schema
tests were skipped, until we fix the data / expand the features of the new data schema
