[VOL-3386] Add support for secure gRPC in openolt-agent
The init script of the openolt service may start with '--enable-tls <TLS_OPTION>' argument for the gRPC server.
Default is insecure with no '--enable-tls' argument.
The TLS capability depends upon the certificates stored at the keystore/ directory: 1. root.crt (CA public key), 2. server.crt (public key), 3.server.key (private key).
Four unit tests are added for the secure gRPC server which work with the keystore-test/ directory.
The certificates stored at the keystore-test/ directory are self-signed certificates, valid until Apr 11 23:16:58 2031 GMT.
