[Frontend] As a User, I can upload a csv file in order to run multiple keyword searches

[Xavier MALPARTY]

Build advanced UI for #9

Why?

Enable the user to save time by processing multiple keywords from 1 single user action (update a file).
Save even more time by processing keywords asynchronously.

Additional notes:

Problems to solve:

• Enable user to run from 1 to 1.000 search queries from 1 single action (upload csf file)
• Enable user to be aware if the selected csf file is not valid
• Enable user to see the file name from a given keyword
• Enable third parts to submit files via API too

No Gos:

• No fancy drag & drop
• No multiple files upload
• No dynamic status progress update [yet]
• No search/filters [yet]
