* Adjust provider and aggregator to copy the used openpgp pubkey into a locally
provided directory `openpgp` beside the `prodiver-metadata.json`.
This more robust and self-reliant than using a public pubkey server,
which is the reason why the CSAF 2.0 csd02 mentions it as example in
"7.1.20 Requirement 20: Public OpenPGP Key".
* Improve aggregator by removing a typo `aggreator` from one written paths.
(Done with this change as it also affects the openpgp/ paths writing.)
solve #85
* Add a first description of the config options for csaf_provider.
* Change option name from `domain` to `canonical_prefix_url`
to make the usage more intuitively. Use`https` in the default,
if unset.
