Update the configuration file format to support several ogServers and
retrieve scopes from those ogServers.
The old config file format is still supported.
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.
