Move feature and module definitions to f_p::module

This moves the definition of foreman_proxy::feature from
foreman_proxy::settings_file to foreman_proxy::module. It also
simplified it by only passing a $module_enabled variable. This is still
needed because it needs to be in context for template().

Introduce foreman_proxy::plugin::provider

This additional abstraction makes it easier to configure plugins that
are providers when they follow conventions.

Introduce foreman_proxy::plugin::module

This introduces a define for plugins that have a package and a config
file, which is most of them.

Declare features on SSH and Pulp modules

Use $f_p::plugin::dynflow::external_core

Since 5bde9c79ca05a7d30fd7ec7a85a109220b4950df there is a variable that
explicitly sets the external core. Rather than copying the logic, this
reuses the variable.

Move Ruby package prefix to params

Rather than redefining the package prefix, this introduces the variable
in params.pp.

Drop group parameter on plugins

Setting the group can be useful if other processes need to read the
file, but for foreman-proxy this is not the case.

Introduce foreman_proxy::globals

This class is intended to allow overriding some parameters that
basically never change. This makes the parameters of init.pp slightly
easier to digest. It also allows testing of some modules by just
including params without the entire foreman_proxy class. This makes...

Document classes using puppet-strings

This doesn't convert all classes since the installer still relies on
rdoc groups. However, not all classes are public and this converts what
makes sense.

Fixes #28877 - Dynamically determine Pulp Puppet dir

This change removes the default value and looks it up at runtime. The
benefit is that we can use the lookup method to get the answer for the
puppet module.

The main driver for this is that the puppet_environmentpath fact has...
