Adds support for `name_prefix` to the `aws_autoscaling_group` and `aws_elb` resources. Unfortunately when using `name_prefix` with `aws_elb`, this means that the specified prefix can only be a maximum of 6 characters in length. This is because the maximum length for an ELB name is 32 characters, and `resource.PrefixedUniqueId` generates a 26-character unique identifier. I was considering truncating the unique identifier to allow for a longer `name_prefix`, but I worried that doing so would increase the risk of collisions.
This update adds ALB support to the
wait_for_elb_capacity/min_elb_capacity options. Target groups are
handled in nearly the same way as Classic ELBs, so the change should be
transparent. This supports both ALB target groups and classic ELBs being
attached to the ASG at the same time.

`enabled_metrics`
Fixes#7693
The metrics_granularity parameter was not being passed to the
`EnableMetricsCollection` when we were calling it from the Update func.
this was causing the API call to silently fail and not update the
metrics for collection - unfortunately the enabled_metrics were still
being added to the state :(
By passing the granularity, we now get the correct metrics for
collection

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.
Fixes a diff calculation error when only a VPC zone
identifiers is provided. In this case the associated
availability zones are computed from the subnets per
the AWS documentation.
It was a mistake to switched fully to `==` when activating waiting for
capacity on updates in #3947. Users that didn't set `min_elb_capacity ==
desired_capacity` and instead treated it as an actual "minimum" would
see timeouts for every create, since their target numbers would never be
reached exactly.
Here, we fix that regression by restoring the minimum waiting behavior
during creates.
In order to preserve all the stated behavior, I had to split out
different criteria for create and update, criteria which are now
exhaustively unit tested.
The set of fields that affect capacity waiting behavior has become a bit
of a mess. Next major release I'd like to rework all of these into a
more consistently named block of config. For now, just getting the
behavior correct and documented.
(Also removes all the fixed names from the ASG tests as I was hitting
collision issues running them over here.)
Fixes#4792
It's a bit confusing to have Terraform poll until instances come up on
ASG creation but not on update. This changes update to also poll if
min_size or desired_capacity are changed.
This changes the waiting behavior to wait for precisely the desired
number of instances instead of that number as a "minimum". I believe
this shouldn't have any undue side effects, and the behavior can still
be opted out of by setting `wait_for_capacity_timeout` to 0.
The `ForceDelete` parameter was getting sent to the upstream API call,
but only after we had already finished draining instances from
Terraform, so it was a moot point by then.
This fixes that by skipping the drain when force_delete is true, and it
also simplifies the field config a bit:
* set a default of false to simplify the logic
* remove `ForceNew` since there's no need to replace the resource to
flip this value
* pull a detail comment from code into the docs
The initial commit of AWS autoscaling group termination policy was
unfinished. It only worked on "create", and so had a needless ForceNew
that would rebuild autoscaling groups on any change. It also used a
HashString set, so it didn't preserve ordering of multiple policies
correctly.
Added the "update" operation, and converted to a TypeList to preserve
ordering. In addition, removing the policy or setting it to a null list
will reset the policy to "Default", the standard AWS policy.
Updated the acceptance tests to verify the update, but the null case is
difficult to test.
