provider/aws: rename local_name_filter attribute to name_regex 

Renamed the local_name_filter attribute to name_regex and made it clear in the
docs that this runs locally and could have a performance impact on a large set
of AMIs returned from AWS.

* `local_name_filter` - (Optional) A regex string to apply to the AMI list returned
by AWS. This allows more advanced filtering not supported from the AWS API.
* `owners` - (Optional) Limit search to specific AMI owners. Valid items are the numeric
account ID, `amazon`, or `self`.

* `name_regex` - (Optional) A regex string to apply to the AMI list returned

filtering is done locally on what AWS returns, and could have a performance
impact if the result is large. It is recommended to combine this with other
options to narrow down the list AWS returns.
