Tilde.Green's Temporary File Upload Service

[jmjl]

After evaluating things, I think we'll do the following:

• Install pingvin-share, and configure it to have accounts from the TGCI keycloak
• When the voting system is ready, make poll to see if users would be interested in having us host pixelfed

I'll install pingvin-share when I get some free time, maybe tomorrow, but it will probably be installed on Saturday.
