[PR #6275/c280b793 backport][stable-6] redhat_subscription: fix D-Bus option for environments on CentOS (#6282) 
redhat_subscription: fix D-Bus option for environments on CentOS (#6275)

Factorize the current logic to determine whether use 'environments' as
D-Bus registration option (rather than 'environment') in an own
function, so it is easier to read it and maintain it.

With the small helper function in place, extend the logic to support
CentOS: it is in practice the same as the RHEL one, with an additional
check to support CentOS Stream 8 (which is a rolling release, and not
versioned).

(cherry picked from commit c280b793de)

module: redhat_subscription
short_description: Manage registration and subscriptions to RHSM using C(subscription-manager)
description:
- Manage registration and subscription to the Red Hat Subscription Management entitlement platform using the C(subscription-manager) command,
registering using D-Bus if possible.
author: "Barnaby Court (@barnabycourt)"
notes:
- In order to register a system, subscription-manager requires either a username and password, or an activationkey and an Organization ID.
- Since 2.5 values for I(server_hostname), I(server_insecure), I(rhsm_baseurl),
I(server_proxy_hostname), I(server_proxy_port), I(server_proxy_user) and
I(server_proxy_password) are no longer taken from the C(/etc/rhsm/rhsm.conf)
config file and default to None.
- It is possible to interact with C(subscription-manager) only as root,
so root permissions are required to successfully run this module.
- Since community.general 6.5.0, credentials (that is, I(username) and I(password),
I(activationkey), or I(token)) are needed only in case the the system is not registered,
or I(force_register) is specified; this makes it possible to use the module to tweak an
already registered system, for example attaching pools to it (using I(pool), or I(pool_ids)),
and modifying the C(syspurpose) attributes (using I(syspurpose)).
requirements:
- subscription-manager
- Optionally the C(dbus) Python library; this is usually included in the OS
as it is used by C(subscription-manager).

C(0123456789abcdef0123456789abcdef: 2). If the quantity is provided, it is used to consume multiple
