Package Agent as .deb for Ubuntu, Debian, etc. Linux distros

[SergeyKleyman]

Package should:

• Install extension binary
• Install PHP part of the agent
• Update php.ini file(s) including setting elastic_apm.bootstrap_php_part_file

Tasks

• PoC -> Package deb/rpm/tar.gz with fpm (1st delivery) #79
• Define what the installation needs to do. -> packaging: debian package installation with post-install #98
• Agree the folder layout. -> See [Packaging] Agent folder structure where the distributions will be installed #107
• Follow-up regarding functional testing and non-functional testing (installing, uninstalling, upgrading ...). See [Packaging] Non functional testing #100
• Support versioning for PRs that are unique and compatible with the package manager. See [Packaging] upgrade compatibility #108
• Create smoke tests to verify the package gets installed as expected.
• Confirm what data to be replaced in the package metadata.

Very first approach to support the package generation with fpm:

• Package deb/rpm/tar.gz with fpm (1st delivery) #79

This has been implemented, so I'll close it now
