newton verson doesn't load existing entry points

Asked by Masha Atakova

Hello everyone,

My problem is that python-watcherclient can't load it's own entry points and some of the custom ones (like strategy entry points created as described [here](https://github.com/openstack/watcher/blob/master/doc/source/dev/plugin/strategy-plugin.rst)).

OS: Centos 7 x64
Installed watcher version:
python-watcher (0.31.0)
python-watcherclient (1.0.0)

Part of `watcher help` result showing problems with own entry points:
```
See "watcher help COMMAND" for help on a specific command.

Commands:

While the entry points actually exist (output provided by entrypoints module and pprint):

```
Is it a problem with configuration in watcher.conf or is it some sort of bug?
Thanks!
