VAULT-9883: Agent Reloadable Config (#18638)
* Update command/agent.go
* Attempt to only reload log level and certs
* Mimicked 'server' test for cert reload in 'agent'

Co-authored-by: Nick Cabatoff <ncabatoff@hashicorp.com>

Left out the `c.config` tweak that meant changes to lots of lines of code within the `Run` function of Agent command. :)

Move version out of SDK. (#14229)
Move version out of SDK.  For now it's a copy rather than move: the part not addressed by this change is sdk/helper/useragent.String, which we'll want to remove in favour of PluginString.  That will have to wait until we've removed uses of useragent.String from all builtins.

fix incorrect use of loop variable (#16872)
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.

refactor: replace strings.Replace with strings.ReplaceAll (#15392)
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.

Agent JWT auto auth remove_jwt_after_reading config option (#11969)
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-5935 agent: redact renew-self if using auto auth (#15380)
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.

Agent error log level is mismatched (#14424)
* [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`.

Add telemetry to Vault agent (#13675)
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

agent: Use an in-process listener with cache (#12762)
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{}.

Move awsutil over to the go-secure-stdlib version (#12128)
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.
