In the next commit I change conf.settings to be initialized
at runtime instead of load time and so any import of
`from lbrynet.conf import settings` will be and stay None if
it happens before the initialization.
For a host to be able to access the daemon running inside a docker
container the damon needs to be listening to 0.0.0.0
- move the API_INTERFACE setting to the adjustablesettings
- check the port matches as well as the interface
- move analytics creation earlier in the startup process
- add several events to track startup, startup failure, other errors
- abstract platform detection into separate file
- add "build" type to platform so we can differentiate devs vs live users
-user starts a httpauthsession with an api key and name
-user initializes jsonrpc hmac secret to sha256 of session id
-server sends new random hmac secret after each api call
-a user without an authenticated session will get a authorization error
