Use RequestSendFailed when fail to parse content type headers

Don't log stack traces for HTTP error responses

* Correctly retry and back off if we get a HTTPerror response

* Refactor request sending to have better excpetions

MatrixFederationHttpClient blindly reraised exceptions to the caller
without differentiating "expected" failures (e.g. connection timeouts
etc) versus more severe problems (e.g. programming errors).

This commit adds a RequestSendFailed exception that is raised when
"expected" failures happen, allowing the TransactionQueue to log them as
warnings while allowing us to log other exceptions as actual exceptions.

* Fix command hint to generate a config file

When trying to start Synapse without a config file, it will complain
and give a hint towards what command to run. This hinted command
is missing the "report_stats" parameter, which is required with either
yes or no value. Add this to the command.

Not an ideal situation but makes the given command work without the
user getting another error, even though it might be unclear what
"report_stats" represents.

Ensure synchrotrons can access is_support_user in the storage layer

Hi, the original docker-compose file did not work by default.
You get federation port working but no client port.

My proposal is to let federation port work as it is by default (8448) and let traefik handle client http/https traffic.

Make sure we don't put the _trial_temp directory in the package target
directory.

Fixes https://github.com/matrix-org/synapse/issues/4322

since #4298, the optional dependencies are no longer installed with a simple
`pip install .`, which meant that they were not being included in the debian
package.

The easy fix to that is dh_virtualenv --extras, but that needs dh_virtualenv
1.1...

* Remove mention of lt-cred-mech in the sample coturn config.

Also clean up some minor formatting issues while I'm here.

Fix test_metrics.py compatibility prometheus_client 0.5

Fix circleci config for synapse:latest docker upload

These settings are not supposed to be under 'listeners'.

Make the dependencies more like a standard Python project and hook up the optional dependencies to setuptools (#4298)

prometheus_client 0.5 has a named-tuple Sample type with more member
than the old plain tuple had. This commit makes sure the unit test
detects this and changes the way it reads the sample.
