Standardize import structure

Standardize on "import module" format rather than "from module import foo" format
Remove _poetry stub module since we directly depend on the poetry package now
Fix conflicts between modules and parameters both named 'poetry'
Fixes #92

"""You've heard of vendoirization, now get ready for internal namespace shadowing
Poetry is an optional dependency of this package explicitly to support the use case of having the
plugin and the `poetry` package installed to the same python environment; this is most common in
containers and/or CI. In this case there are two potential problems that can arise in this case:
* The installation of the plugin overwrites the installed version of Poetry resulting in
compatibility issues.
* Running `poetry install --no-dev`, when this plugin is in the dev-deps, results in poetry being
uninstalled from the environment.
To support these edge cases, and more broadly to support not messing with a system package manager,
the `poetry` package dependency is listed as optional dependency. This allows the plugin to be
installed to the same environment as Poetry and import that same Poetry installation here.
However, simply importing Poetry on the assumption that it is installed breaks another valid use
case: having this plugin installed alongside Tox when not using a Poetry-based project. To account
for this the imports in this module are isolated and the resultant import error that would result
is converted to an internal error that can be caught by callers. Rather than importing this module
at the module scope it is imported into function scope wherever Poetry components are needed. This
moves import errors from load time to runtime which allows the plugin to be skipped if Poetry isn't
installed and/or a more helpful error be raised within the Tox framework.
