Generate Event Plan web page User story

[Govind-Asawa]

Things done

• Made the sidebar little dynamic to add new items
• Added link to Event creation page in the sidebar
• Created the page with following features
  • Suggestions: each suggestion is a component. We can dynamically add or remove suggestions
  • Clicking on a suggestion pre-fills the input field
  • clicking on generate button, requests /api/chatbot/gen-event endpoint, receives response and shows it on the screen
  • While the frontend waits for suggestion, loader is displayed to the user, as shown in the attached fig

NOTE: Added a new npm lib react-loader-spinner
