CloudRetry/AWSRetry backoff decorator with unit tests (#17039)

Browse source

* Added aws_retry decorator function with unit tests

* Restructured the code to be used with a base class.

This base class CloudRetry can be reused by any other cloud provider.
This decorator should be used in situations, where you need to implement
a backoff algorithm and want to retry based on the status code from the
exception.

* updated documentation

* fixed tabs

* added botocore and boto3 to requirements.txt

* removed cloud.py from py24 tests, as it depends on boto3

* fix relative imports

* updated test to be 2.6 compat

* updated method name from retry to backoff

* readded lxd

* Updated default backoff from 2 seconds to 1.1s.

This will be about a total of 48 seconds in 10 tries. This is
configurable.
