New Relic: add debug options as environment variables

Changed:

• NewRelic support sometimes requires more debug logging and special flags set to get all the debug logs it needs. This PR gives the ability to set more NewRelic verbose logging options via environment variables.

7.3+: configurable log length and buffering

Changed:

• Improved FPM validation to prevent building or launching with bad configuration
• Improved shutdown behavior based on docker-base guidance
• PHP 7.3-only: leveraging new directive decorate_workers_output to not have to manually cleanse stdout/stderr streams, added PHP_FPM_LOG_LIMIT and PHP_FPM_LOG_BUFFERING environment variables. See README for usage
• PHP 7.3: created workaround for goss YAML deep merge bug/feature

Tests: Upgrade base / Refactor tests

Changes:

• Base upgraded from 8.2 --> 8.3
• Tests refactored to uplevel, using env variables, removed package-based checks
• Alpine: php mods upgraded to latest stable, matching other variants

Security: Replace phpinfo()

Changes

PHP

• Replace phpinfo() in default index.php with a echo of PHP_VERSION

  By default phpinfo can expose credentials in environment variables. An unsuspecting developer may accidentally deploy without replacing this index.php first. Using echo is a safer option.

New Relic: tracing managed by environment variables

Changes

All Variants:

• New Relic offers the ability for automatic tracing of calls between services. An environment variable config was added to enable this feature.
