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

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.
For situations where you want the Vault agent to handle one or more templates but do not require the acquired credentials elsewhere.
Modify the logic in SyncServer so that if there are no sinks, ignore any new credentials. Since SyncServer is responsible for shutting down the agent, make sure it still properly shuts down in this new situation.

This allows it to authenticate once, then exit once all sinks have
reported success. Useful for things like an init container vs. a
sidecard container.
Also adds command-level testing of it.
