What does this PR do?

This allows users to make multi-city trip requests.

How should this be manually tested?

• Clone the branch to your local repository
• Run npm install to install node packages
• Using any API testing tool (eg postman, insomnia) make a POST request to the localhost:3000/api/v1/request/multi-city

category:  multi-city   // must be multi-city
origin: {string}
destination: [array]
departure_date: {string}   // e.g. 02-02-2020
return_date: {string}   // e.g. 03-05-2021
reason: {string}
room_id: {integer}

Any background context you want to provide?

This route is protected, so you need to be logged in to call it. The token will be pulled from
Authorization: <token>. Make sure to add it there. To make a request, you need a valid room_id.
