Issue: IAM - create_policy returns bad tags
Hi, Thank you for this great library!

I just noticed a small bug in IAM implementation. Using latest moto version with python mocks. 
The function create_policy returns the policy tags with this format: 
`[{"tag_key": {"tag_key": "tag_value"}},...]` instead of `[{"tag_key": "tag_value"}]`

I took a quick look at the code and seems like the function `policy.get_tag()` that does the conversion is never called and instead the response template use the `tags` attribute from the `Policy` class which is in the wrong format.

So an easy fix would be to do like `get_policy` response template and use get_tags() (in `create_policy` response template). Replacing:

```jinja
{% for tag_key, tag_value in policy.tags.items() %}
``` 
by
```jinja
{% for tag_key, tag_value in policy.get_tags().items() %}
``` 

There might be more like this in IAM looking at the templates but I did not dig further.
