[PR #7624/af01b462 backport][stable-7] redhat_subscription: use D-Bus registration on RHEL 7 only on 7.4+ (#7642) 
redhat_subscription: use D-Bus registration on RHEL 7 only on 7.4+ (#7624)

subscription-manager does not provide a D-Bus interface in versions of
RHEL 7 older than 7.4.

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:
- |
The module tries to use the D-Bus C(rhsm) service (part of C(subscription-manager))
to register, starting from community.general 6.5.0: this is done so credentials
(username, password, activation keys) can be passed to C(rhsm) in a secure way.
C(subscription-manager) itself gets credentials only as arguments of command line
parameters, which is I(not) secure, as they can be easily stolen by checking the
process listing on the system. Due to limitations of the D-Bus interface of C(rhsm),
the module will I(not) use D-Bus for registration when trying either to register
using O(token), or when specifying O(environment), or when the system is old
(typically RHEL 7 older than 7.4, RHEL 6, and older).
- 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 O(server_hostname), O(server_insecure), O(rhsm_baseurl),
O(server_proxy_hostname), O(server_proxy_port), O(server_proxy_user) and
O(server_proxy_password) are no longer taken from the C(/etc/rhsm/rhsm.conf)
config file and default to V(null).
- 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, O(username) and O(password),
O(activationkey), or O(token)) are needed only in case the the system is not registered,
or O(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 O(pool), or O(pool_ids)),
and modifying the C(syspurpose) attributes (using O(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).

Specify a subscription pool name to consume. Regular expressions accepted.
Mutually exclusive with O(pool_ids).

Please use O(pool_ids) instead: specifying pool IDs is much faster,

support quantities.

This option is deprecated for the reasons mentioned above,

pool_ids:
description:

Specify subscription pool IDs to consume. Prefer over O(pool) when possible as it is much faster.
A pool ID may be specified as a C(string) - just the pool ID (for example V(0123456789abcdef0123456789abcdef)),
or as a C(dict) with the pool ID as the key, and a quantity as the value (for example
V(0123456789abcdef0123456789abcdef: 2). If the quantity is provided, it is used to consume multiple
entitlements from a pool (the pool must support this). Mutually exclusive with O(pool).
