Please expose (promisified) waitForReady

[FauxFaux]

The grpc client (channel?) has a waitForReady(deadline) method, which loops around waiting for the connectivityState to go to ready.

Please expose this on channel, preferably promisified, so I don't have to copy-paste it into my codebase.

I have just found waitForChannelReady, which is probably acceptable as a workaround. I completely failed to find it in the search before raising this issue.

Hi @FauxFaux!

Apparently we didn't document this function. We will fix that.

When you say "workaround", do you mean that you have some other API in mind?
