[ansible-project] Failed to install rpm package with yum module

[Tim John]

Hey guys, I've encountered a weird problem with *yum *module.

Working environment:
*OS*: CentOS 6.4
*Kernel*: 2.6.32-358.e16.x86_64
*Ansible*: 2.0.0 (devel b37be236d9) running from source

I'd like to install *Erlang *in *CentOS 6.4*, to do that "
*erlang-solutions-1.0-1.noarch.rpm*" must be installed first, which would
add an extra repo entry (named *erlang_solutions.repo*), through that repo,
we can install *Erlang*.

So, here is what I'm doing in my playbook:

```
- *name*: install erlang-solutions
*yum*: *name*=
http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
*state*=present
```

this task will be executed without any error, and the "
*erlang-solutions-1.0-1.noarch.rpm*" will be installed on the destination
host.
running `*yum list installed | grep erlang*`, and the result is:

```
erlang-solutions.noarch 1.0-1 installed
```

BUT !!!!! There no extra repo entry added to `*/etc/yum.repos.d*`, so, I
still can't install *Erlang*.

Forget to say, that after install "*erlang-solutions-1.0-1.noarch.rpm*"
with rpm command directly on the host, like:

```
wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
```

an extra yum repo entry named *erlang_solutions.repo* will be added to `
*/etc/yum.repos.d*`.

Thank you, guys
