would bubble up from e.g. JSON parsing, etc.

* Add JSON validation to the aws_cloudwatch_event_rule resource.
This commit adds support for new helper function which is used to

to wrap around the aforementioned helper.

* Re-factor validation function.
This commit changes the logic of the function so that it would check length of
the normalised JSON string over the given string, plus short-circuit early
should JSON would not be valid.

Normalise the event_pattern of the aws_cloudwatch_event_rule resource
before uploading it to AWS.
AWS seems to accept a event_pattern with a JSON with new lines, but then
the rule does not seem to work. Creating the rule in the AWS console works,
but will setup the pattern as a json without newlines or spaces, and
display a formatted JSON.
Change the `RetryFunc` from a plain `error` return type to a
specialized `RetryError` which must decide whether it is
retryable or not.
Add `RetryableError` / `NonRetryableError` factory functions that
callers are meant to use to build up these errors.
This makes it eminently clear whether or not a given error is
retryable from inside the client code.
Goal here is to _not_ change any behavior, simply reflect the
existing behavior with the new, clearer, API.
All of these RetryErrors were meant to fail right away, but instead
caused retry looping because the typecheck in the implementation of
`resource.Retry()` only catches the value type, and not the pointer
type.
