This fixes a couple of references to loop variables in parallel tests
and deferred functions. When running a parallel test (calling
`t.Parallel()`) combined with the table-driven pattern, it's necessary
to copy the test case loop variable, otherwise only the last test case
is exercised. This is documented in the `testing` package:
https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks
`defer` statements that invoke a closure should also not reference a
loop variable directly as the referenced value will change in each
iteration of the loop.
Issues were automatically found with the `loopvarcapture` linter.
* OSS portion of wrapper-v2

* Rename the OveriddenType to WrapperType and use it for the barrier type prefetch
* Fix unit test
strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

Add a new config option for Vault Agent's JWT auto auth
`remove_jwt_after_reading`, which defaults to true. Can stop
Agent from attempting to delete the file, which is useful in k8s
where the service account JWT is mounted as a read-only file
and so any attempt to delete it generates spammy error logs.
When leaving the JWT file in place, the read period for new
tokens is 1 minute instead of 500ms to reflect the assumption
that there will always be a file there, so finding a file does not
provide any signal that it needs to be re-read. Kubernetes
has a minimum TTL of 10 minutes for tokens, so a period of
1 minute gives Agent plenty of time to detect new tokens,
without leaving it too unresponsive. We may want to add a
config option to override these default periods in the future.

Vault agent redacts the token and accessor for `/auth/token/lookup-self` (and `lookup`)
if the token is the auto auth token to prevent it from leaking.
Similarly, we need to redact the token and accessor from `renew-self`
and `renew`, which also leak the token and accessor.
I tested this locally by starting up a Vault agent and querying the
agent endpoints, and ensuring that the accessor and token were set to
the empty string in the response.
* [VAULT-1618] Agent error log level is mismatched
`logLevelToStringPtr` translates `go-hclog`'s `ERROR` to `"ERROR"` for
Consul Template's runner, but that expects `ERR` and is quite strict
about it.
This will address https://github.com/hashicorp/vault-k8s/issues/223
after it is set as the default image in `vault-k8s`.
I didn't find a simple way to test this other than starting up a full
server and agent and letting them run, which is unfortunately fairly
slow.
I confirmed that this addresses the original issue by modifying the helm
chart with the values in this commit and patching the log level to `err`.

This patch adds a new /agent/v1/metrics that will return metrics on the
running Vault agent. Configuration is done using the same telemetry
stanza as the Vault server. For now default runtime metrics are
returned with a few additional ones specific to the agent:
- `vault.agent.auth.failure` and `vault.agent.auth.success` to monitor
the correct behavior of the auto auth mechanism
- `vault.agent.proxy.success`, `vault.agent.proxy.client_error` and
`vault.agent.proxy.error` to check the connection with the Vault server
- `vault.agent.cache.hit` and `vault.agent.cache.miss` to monitor the
cache
Closes https://github.com/hashicorp/vault/issues/8649

Uses a bufconn listener between consul-template and vault-agent when
caching is enabled and either templates or a listener is defined. This
means no listeners need to be defined in vault-agent for just
templating. Always routes consul-template through the vault-agent
cache (instead of only when persistent cache is enabled).
Uses a local transportDialer interface in config.Cache{}.

Unlike the other libraries that were migrated, there are no usages of
this lib in any of our plugins, and the only other known usage was in
go-kms-wrapping, which has been updated. Aliasing it like the other libs
would still keep the aws-sdk-go dep in the sdk module because of the
function signatures. So I've simply removed it entirely here.

Remove template_retry config section. Add new vault.retry section which only has num_retries field; if num_retries is 0 or absent, default it to 12 for backwards compat with pre-1.7 template retrying. Setting num_retries=-1 disables retries.
Configured retries are used for both templating and api proxy, though if template requests go through proxy (currently requires persistence enabled) we'll only configure retries for the latter to avoid duplicate retrying. Though there is some duplicate retrying already because whenever the template server does a retry when not going through the proxy, the Vault client it uses allows for 2 behind-the-scenes retries for some 400/500 http error codes.
The existing code would retain the previous backoff value even after the
system had recovered. This PR fixes that issue and improves the
structure of the backoff code.
