Send full logs as an attachment to our dogfood instance

[hubertdeng123]

This change allows us to support sending envelopes to our sentry dogfood instance.

1. An envelope file is created with envelope headers
2. Log file contents are dumped into the file as the attachment payload
3. File is deleted

Sample log here:

I'm not sure I agree we should delete the envelope, if someone runs into an error, tries to fix it, runs again and hits the same error, we don't want 2 envelopes I don't think. I originally put the envelope file in /tmp so that they will get cleaned up periodically but while someone is working on an issue we don't send multiple.

I see your point there, my thought for deleting the file was that it's possible to have the same traceback but a different error and in that case I think we should send both. What we could do is determine the event id using both the traceback hash and error. It actually is probably better that way since we have to scroll through all the events to see what kind of errors people are seeing on a certain line. Then we don't have to delete the file

I agree this makes a lot of sense.

Looks great!
