Regression: Additional GRPC options can't be set anymore in Nestjs 7

[sjkummer]

Bug Report

Original behavior in Nestjs 6

In Nestjs 6, it was possible to set all GRPC options, e.g. grpc.ssl_target_name_override and grpc.default_authority which are required to have GRPC-SSL enabled on localhost:

const grpcOptionsAny: any = grpcClientOptions.options;
grpcOptionsAny['grpc.ssl_target_name_override'] = 'localhost';
grpcOptionsAny['grpc.default_authority'] = 'localhost';

Breaking change

The commit 0b38029 changed this behavior by removing ...this.options from the used option-Object:

0b38029#r38494866

Now, most of the GRPC-options are unavailable when using Nestjs:

Would you like to create a PR for this issue? Perhaps, we should also add other missing gRPC options to the GrpcOptions interface (to avoid as any cast). Would you be interested in contributing to this?

@kamilmysliwiec The list of GRPC options is quite long, but I can do an easy PR which will at least avoid casting.
