implement reload by sending the HUP signal

[gdamjan]

According to the 0.99 release info synapse now uses the HUP signal to reload certificates:

Synapse will now reload TLS certificates from disk upon SIGHUP. (#4495, #4524)

So the matrix-synapse.service unit file should include a reload directive.

Thanks. Can you add an entry to the debian/changelog?

[gdamjan]

I'm not sure how that should look, do I put myself as signed?

[richvdh]

Probably best to use dch. Try something like dch -v 0.99.1, which will start an UNRELEASED version, and put your name in the maintainer field. It will then open an editor where you can add a suitable entry in the template it gives you.

Later, when we come to do the next release, dch will then put our email address back in the maintainer field and record your contribution like this.
