Implementing sessions layout for public events(UI) about open-event-frontend

[niranjan94]

Requirements:

• Each session in a component

• Session List will be a component

• The date from the speaker object can be converted to human readable format using ember-moment helpers already included in the project.

• Sessions to be displayed in chronological order

• Filtering by session type need not be done now and can be done in a seperate PR. Your choice. No compulsion.

• For speaker information either longBiography or shortBiography or speakingExperience might be available in the API. Display only one of what is available in the order of preference. shortBiography > longBiography > speakingExperience.

• sessions array (with dummy sessions data) in the session controller. The following can be a session object. You don't have to cover all the fields in the dummy object. Just use the one's you'd be using in the UI for now.

   {
     "id": 0,
     "longAbstract": "string",
     "session_type": {
       "length": "11:00",
