* [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`.

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
