The name parameter is optional for the CopyImage API call of ec2.

Make the name parameter optional for the copy_image method. The default value is the same as that
of the source AMI being copied [1].

s3put: accept headers values containing "="

s3put tries to split headers on the "=" sign. Some headers include a "=" sign (e.g. max-age), and can't be used. 

This pull request splits on the first equal sign to support those.

Caveat: if a user uses the command correctly (`s3put --header "header1=value1 header2=value2"), they won't get an exception.

Add unit test for the CopyImage API.

The test case covers two scenarios:
    1. Where all the parameters are passed to the API call.
    2. Where the name parameter is skipped. As per the
    documentation, the name of the source AMI will be used in such a
    case.
