Initial version of Calendar notification for review, and it includes the calendar event for start workflow.
Please follow steps for installing Google python client library for calendar service API under src/
This needs to be added to deployment step to AppEngine.
Refer to https://developers.google.com/api-client-library/python/start/installation#appengine
Created WorkflowCalendarService in ggrc_workflows/notification and create calendar events for WF/TaskGroup during start workflow cycle
It is ready for integration with UI, REST API is POST /calendar/workflow/<id>.
Currently it sends OK or Error in render response. Needs ot be modified to point to correct HAML template as part of E2E integration with UI.
The reminders and updates to calendar events are pending
Removing session cookie fields such as resource and id for creating calendar event for 2 step flow authorization

Broken, saving current work

Program is jammed between a mapping and an actual relationship. Need to
clarify this with Dan/Brad.
Modal should work properly when relationship with Program is corrected.
Mixed risk_assessments into Program
Progress on tier2 mustache for risk_assessments
Merge with latest code base, use extension modules for notification, add dependencies to http2lib and google python client library
This contains calendar backend for creating calendar events for workgroup/taskgroup at the start of the workflow, also uses extension modules to avoid ggrc.workflows in views, this can be starting point for UI integration for calendar.
Merge remote-tracking branch 'origin/feature/email_notification_task_undo' into feature/calendar_notification
