authorize: use jwt insead of state struct (#514)

Browse source 
authenticate: unmarshal and verify state from jwt, instead of middleware
authorize: embed opa policy using statik
authorize: have IsAuthorized handle authorization for all routes
authorize: if no signing key is provided, one is generated
authorize: remove IsAdmin grpc endpoint
authorize/client: return authorize decision struct
cmd/pomerium: main logger no longer contains email and group
cryptutil: add ECDSA signing methods
dashboard: have impersonate form show up for all users, but have api gated by authz
docs: fix typo in signed jwt header
encoding/jws: remove unused es256 signer
frontend: namespace static web assets
internal/sessions: remove leeway to match authz policy
proxy:  move signing functionality to authz
proxy: remove jwt attestation from proxy (authZ does now)
proxy: remove non-signed headers from headers
proxy: remove special handling of x-forwarded-host
sessions: do not verify state in middleware
sessions: remove leeway from state to match authz
sessions/{all}: store jwt directly instead of state
