[Jaeger] Add X-Request-ID to the metadata

[michaelstingl]

All ownCloud (desktop-/mobile-/web-)clients already send X-Request-ID HTTP header with every request. They're shown in the client logfiles, and in the beginning of every line of the owncloud.log. They can also be easily added to the Apache log and to the logs from various middleware.

As far as I know, they're not really used from oCIS yet. (maybe in the logs?)

A beginning could be, to add the X-Request-ID HTTP header to the Jaeger metadata…

In the future, clients could also support opentelemetry.io:

• Support opentelemetry.io client#7595
• Support opentelemetry.io  android#2723
• Support opentelemetry.io ios-app#563

@butonic the API test suite is sending X-Request-Id nowadays.
Is the server logging it yet, when things go wrong?

The X-Request-ID was added to the first span and to all possible log output.
