Display progress of Quick Upload

[lidel]

There should be some form of visual feedback when user is uploading a big file.

Adding a progress indicator should be possible when changes listed in ipfs-inactive/js-ipfs-http-client#608 are released 🤔

What ought to be the file-size recommendations/limits for file uploads?

This remains an open question.

I suspect there will be different choke points depending on what IPFS node type is used:

• If extension is set up to use external IPFS node, then we have potential transfer speed limits introduced by js-ipfs-api (HTTP API Client library) and then storage characteristics of go-ipfs come to play.
• If embedded js-ipfs is used, then we have limits imposed by browser vendor on memory use and max local storage size per extension.

In addition to the above, if upload is performed via window.ipfs object, then there might be some overhead introduced by ipfs-postmsg-proxy.

Expect these specific setups to be benchmarked at some point, but looking at https://benchmark-js.ipfs.io I am rather optimistic about every day use.

Progress indicator shipped with v2.3.0. Works best with embedded nodem but external node users should also get some benefit.
There are remaining issues such as long buffering when external node is used, but these things will be addressed in upstream libraries.
