Integrate forms components from case file project

[aniri]

• add a new menu entry - forms
• reuse as much of the code as possible from https://github.com/code4romania/case-file-web
• needed functionality:
  • view forms list
  • add new form
  • edit form (not yet implemented in case file, it is in progress)
  • delete form (not yet implemented in case file, it is in progress)
• adjust data model in order to be aligned with MV data model - https://app-vmon-api-dev.azurewebsites.net/swagger/index.html
• add functionality for missing question types, the ones in MV are:

  QuestionTypes
  0 - multiple choice
  1 - single choice
  2 - single choice + free text
  3 - multiple choice + free text

• Please focus mainly on functionality and not design issues, but keep in mind that this will be the final MV design: https://www.figma.com/file/61NHR7fwmV1Dsv4Pb6F8T7/code4ro_mv_user-management_2018.04.21-(Copy)?node-id=1095%3A688
