Zombie dbus processes generated by github.com/99designs/keyring

[biazmoreira]

Referencing/re-opening the issue #773:

gosnowflake added https://github.com/99designs/keyring as a dependency and, unfortunately, this library has an 99designs/keyring#103 which can lead some Linux systems to create zombie dbus processes. This issue was observed initially when importing the Apache Pulsar client library into Benthos as described redpanda-data/connect#1184 and it's triggered in one of the init() functions from github.com/99designs/keyring.

This is causing Vault to run into the fs.inotify.max_user_instances limit or fd limits causing issues for systemd. See hashicorp/vault#22560
