kytos napps install kytos/<napp> results in SSL certificate error

[viniarck]

Some FIU students have reported this issue, it turns out that https://napps.kytos.io/ certificate has been expirated, so this part of setting installing a NApp doesn't work, since our team doesn't expect to maintain this server, I think we should update the docs to install the NApp from the filesystem instead. Also the git clone commands are still using the old repos.

closing this issue since we're recommending to install directly from GitHub for now as documented in the tutorials.
