* Simplify admin server feature-flagging in #1642

* Rather than push feature flagging down into the `serve` logic, we can
  avoid even matching the logs.json endpoint when the feature isn't
  disabled. This avoids the need for conditional feature gatingc in the
  handler.
* The log module is split into two submodules: level and stream. The
  stream module is feature-gated. This allows to extract function-local
  defintions into the module, which simplifies scoping and makes things
  easier to read (imo).

This release fixes a problem with HTTP/1.1 `CONNECT` requests. When a
server responds to a `CONNECT` request with `content-length` or
`transfer-encoding` headers (in violation of RFC 7231), the proxy must
actively strip these headers to avoid making the Hyper server fail the
response.

This release also fixes an issue with the way proxies discover control
plane components via DNS. When `SRV` records cannot be resolved, the
proxy would no not necessarily fall back to resolving `A` records. This
has been fixed.

Finally, the inbound proxy can now discover policies dynamically. Ports
that are configured in the `LINKERD2_PROXY_INBOUND_PORTS` are discovered
as the proxy starts up; but now the proxy will discover policies for
ports that are not in this list. The pod's default policy is used
initially, but once a policy is received from the control plane it is
used.
