Previously a token could've expired in the middle of an object.PUT
stream, leading to upload being interrupted. This is bad, because user
doesn't always now what is the right values for the session token
lifetime. More than that, setting it to a very high value will
eventually blow up the session token database.
In this commit we read the session token once and reuse it for the whole
stream duration.
