Remove setting of TracerProvider in samples where it is actually not needed as the global TracerProvider should be preferred on default.

I found it also inconsistent to set a TracerProvider but no MeterProvider.

 The instrumentation serializes the whole command into a Span attribute called `db.statement`. The standard serialization format is `{cmdName} {cmdArgs.join(',')}`.
 It is also possible to define a custom serialization function. The function will receive the command name and arguments and must return a string.
