Support Linux stripped symbol debugging

[michaelmaguire]

Split out from #4047 (comment) "Support Microsoft Symbol Server integration with Artifactory for Conan packages containing .pdb" which covers Windows specifically.

We would like to ensure that developers can debug production Linux software published internally using Conan.

Can we please request a Conan/Artifactory integration enhancement that would allow .pdb files published within Conan packages to be transparently available as if it were a Linux symbol server

Looks like a way of doing this is covered here: https://youtu.be/xTmAknUbpB0?t=1913

To help us debug your issue please explain:

• I've read the CONTRIBUTING guide.
• I've specified the Conan version, operating system version and any tool that can be relevant.
• I've explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

The linked video is slightly outdated as there is now an official symbol server for Linux elf binaries called debuginfod. See https://sourceware.org/elfutils/Debuginfod.html and https://developers.redhat.com/blog/2019/10/14/introducing-debuginfod-the-elfutils-debuginfo-server.
