The main motivation behind this change is to get just a little
telemetry information from nodes on the network, namely the version
of Radicle they are running.
This is achieved by rewriting `impl Default for UserAgent` which now
uses the version information provided by the build script also used
in other crates.
Also, a new configuration option `node.userAgent` is added, which
allows users to override the user agent if they so please, or set
the value `null`, which will in turn send the user agent
`/radicle/`, which is not really helpful, and the default prior to
this commit.
Creations of `UserAgent` in the whole workspace is cleaned up. In
order to do that `UserAgent::test` is introduced.
The intent to drop outgoing connections is modeled as `Option::None`
which is brittle and easy to miss.
Extend `enum AddressConfig` with a variant that is more explicit.
Add a configuration knob `node.fetch.signedReferences.featureLevel.minimum` to
allow node operators to enforce more strict verification when fetching
Signed References.
Adds the `rad config schema` to the `rad-config` test so that changes
to the schema will result in errors, forcing the implementor to ensure
the changes are correct.
