Bug#1072321: add package for opentelemetry/otlp (and other grpc modules?)

[David Mandelberg]

Hi,

Sorry for the noise, but I learned about the axosyslog fork (which I 
just filed https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1072543 
for) after I filed this bug. The OTLP features that I want to use look 
like they'll be in axosyslog but not syslog-ng, so I'm not sure I 
actually care about an otlp package for syslog-ng. Should I close this bug?
