Turns out the BC code allowed users to move from `filename` to
`template` to squash the warning without having to switch from template
paths to template contents.
Here we warn when `template` is specified as a path so we can remove the
functionality in the future and remove this source of confusion.

Previously this resource managed the set of keys as a whole rather than
the individual keys, and so it was unable to recognize when a particular
managed key is removed and delete just that one key from Consul.
Here this is addressed by recognizing that each key actually has its own
lifecycle, and detecting when individual keys are added and removed
without replacing the entire consul_keys instance.
Additionally this restores the behavior of updating the "value" attribute
on read, but restricts it only to blocks that already had a value so as
to avoid the quirkiness seen previously when we updated blocks that were
intended to be read-only. Updating the value is important now, because we
rely on this to detect and repair discrepancies between values stored in
Consul and values given in the configuration.
This change produces a change in the handling of the "delete" attribute.
Before it was considered only when the entire consul_keys resource was
deleted, but now it is considered also when a particular key block is
removed from within a resource.
This deals with some of the quirks of interacting with the Consul API,
with the goal of making the consul_keys resource implementation, and
later the consul_keys data source, less noisy to read.
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.
