Fixes: #4441
This fixes the issue with Connect Managed Proxies + ACLs being broken.
The underlying problem was that the token parsed for most http endpoints was sent untouched to the servers via the RPC request. These changes make it so that at the HTTP endpoint when parsing the token we additionally attempt to convert potential proxy tokens into regular tokens before sending to the RPC endpoint. Proxy tokens are only valid on the agent with the managed proxy so the resolution has to happen before it gets forwarded anywhere.

Also change how loadProxies works. Now it will load all persisted proxies into a map, then when loading config file proxies will look up the previous proxy token in that map.
UUID auto-generation here causes trouble in a few cases. The biggest being older
nodes reregistering will fail when the UUIDs are different and the names match
