config: use from_json to read ogserver config

This patch introduces the usage of Flask.Config class so the config can
be read at startup (__init__) only once. Config keys must be uppercase
so that from_json method does take it into account.

Prior to this patch each request required opening and closing the
ogserver.json file via load_config in views.py.

In the future the decorated load_config function inside views.py
may be removed to avoid creating multiple instances of the OGServer
class.
