* Introduce TLS Settings for go-micro based grpc services and clients
TLS for the services can be configure by setting the OCIS_MICRO_GRPC_TLS_ENABLED"
"OCIS_MICRO_GRPC_TLS_CERTIFICATE" and "OCIS_MICRO_GRPC_TLS_KEY"
enviroment variables.
TLS for the clients can configured by setting the "OCIS_MICRO_GRPC_CLIENT_TLS_MODE"
and "OCIS_MICRO_GRPC_CLIENT_TLS_CACERT" variables.
By default TLS is disabled.

* Unify TLS configuration for all grpc services
All grpc service (whether they're based on reva) or go-micro use the
same set of config vars now.
TLS for the services can be configure by setting the OCIS_GRPC_TLS_ENABLED,
OCIS_GRPC_TLS_CERTIFICATE and OCIS_GRPC_TLS_KEY enviroment variables.
TLS for the clients can configured by setting the OCIS_GRPC_CLIENT_TLS_MODE
and OCIS_MICRO_GRPC_CLIENT_TLS_CACERT variables.
There are no individual per service config vars currently. If really
needed, per service tls configurations can be specified via config file.

This avoids using a public global variable. It allows us to initialize
the default client a bit later (outside of init()). That way we can e.g.
properly initialize the in-memory registry.
