Subject: feat(python-plugin): prepend instead of append ModulePath to sys.path
X-Git-Tag: collectd-5.5.0~173^2~1

feat(python-plugin): prepend instead of append ModulePath to sys.path

When importing a module, you expect the plugin repertory to have higher priority
than your site-packages. It will prevent hard to debug clashing module names problems.
At least, if there is a problem, it will fail more loudly than "module did not register
any config callback"
