Remove duplicate docs in digital ocean module.

The EXAMPLES block here has two copies of the same docs,
one nicely formatted, the other less so.

It looks like a pass was made to clean up the docs but the old
cruftier ones were never removed.

apt_repository: added option update_cache.

The default behavior is to update_cache if changed.

If you add more then one repo, you may not want to update cache for every repo separately.
So you can now disable update_cache with this new option e.g. update_cache=no

Updating cache can also be handled using the apt module.
