[LIBCLOUD-712] Use get() to take signature version
The pop() call will remove the field from the REGION_DETAILS dictionary,
causing subsequent calls to use the default value.
> EC2 driver modifies region details

> Key: LIBCLOUD-712
> URL: https://issues.apache.org/jira/browse/LIBCLOUD-712
> Project: Libcloud
> Issue Type: Bug
> Components: Compute
> Reporter: Maarten van Schaik
>
> When creating an EC2 connection, the signature version is taken from the
> region details using a pop-operation. This modifies the configuration:
> subsequent connections will not have the signature version available and will
> fall back to version 2.
> Example:
> {code}
> from libcloud.compute.drivers.ec2 import EC2NodeDriver
> drv = EC2NodeDriver('abc', region='eu-central-1')
> print drv.signature_version
> drv2 = EC2NodeDriver('abc', region='eu-central-1')
> print drv2.signature_version
> {code}
> Prints:
> {code}
> 4
> 2
> {code}
