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

Changes the error output for the second open of the persistent cache
file, to differentiate it from the c.UI.Error message for the initial
open of the cache file, just to make it easier to tell where a problem
occurred.
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{}.

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.
Adds the option of a write-through cache, backed by boltdb
