Version 5.0.2:
- Fix: healthcheck (and other subcommands) not working when api.cli is enabled
When exabgp.api.cli is true, the exabgp_cli_pipe environment variable was
inherited by all child processes, causing 'python -m exabgp healthcheck'
to run the CLI pipe code instead of the healthcheck subcommand.
Only the internal CLI process now receives this variable.
