mount.

return the most up-to-date info about an instance when starting/stopping it

otherwise the module will return the info about the instance that it got prior to the action taken
So if you had a task to start an instance:

      ec2:
         instance_ids: ...
         state: running
      register: ec2_info

the registered data would have empty public_dns_name, public_ip, private_dns_name, private_ip
Remove whitespace around args

More info in "not a legal parameter" error

Without this, I was getting:

```
ERROR: apt is not a legal parameter in an Ansible task or handler
```

which doesn't give me any idea what task ansible is having trouble with
(I reference "apt" many times in many roles)

With this, I get:

```
ERROR: "apt" is not a legal parameter in an Ansible task or handler
    task name: "Update apt-get cache"
    line: "apt: update_cache=yes cache_valid_time=86400"
    role_name: "common"
```

which points me right at the task that ansible is having trouble with.
