Replace credentials.enabled with credentials.identity - #310

Conversation
local.credentials.identity controls whose credentials the local Temporal
server sees, in the "authorization" and "authorization-extras" headers:
caller (default) forward whatever the caller sent; add nothing
proxy drop forwarded credentials and send the
CredentialProvider's instead
none drop forwarded credentials and send none
With identity "proxy", a replication stream forwarded from the remote side
reaches the local server with only the proxy's token, never with a token
the remote side sent. Forwarded credentials are removed by a client
interceptor that runs before gRPC adds the per-RPC credentials, so the
proxy's own token is never stripped.
Validation rejects unknown identities, identity "proxy" on a non-TCP local
connection, and any remote.credentials block. The proxy refuses to start
with identity "proxy" and no CredentialProvider.

Rename CredentialIdentityCaller to CredentialIdentityDefault ("default"),
which forwards the caller's credentials and applies when identity is not
set, and CredentialIdentityNone to CredentialIdentityStrip ("strip").
Rename auth.ForwardedCredentialHeaders to auth.CredentialHeaders.
