This PR resolves#7629
This adds javaagent instrumentation for the
[jodd-http](https://http.jodd.org/) `HttpRequest`.
It creates `Http Client Spans` and `Http Client Metrics`, the lowest
supported version is `org.jodd:jodd-http:4.2.0` (most recent: `6.3.0`),
since this is the first version of the library supporting java 8, having
follow-redirect capability and `HttpRequest#overwriteHeader()` method.
The instrumented method's signature and return type `HttpRequest#send()`
has not been modified since, and therefore the instrumentation works for
all `jodd-http` versions above `4.2.0`.
Since this is my first contribution/instrumentation, I orientated myself
on the `apache-httpclient-5.0` instrumentation, but obviously I would be
glad to get some feedback on this
