Problem: Nitro enclave environment arguments are not documented

[tomtau]

Right now, the default Dockerfile executes the enclave without any arguments: https://github.com/crypto-com/tmkms-light/blob/main/Dockerfile.nitro#L246

With that Dockerfile, default choices will be used: https://github.com/crypto-com/tmkms-light/blob/main/providers/nitro/nitro-enclave/src/main.rs#L15

1. the enclave code will listen on the vsock port 5050 for the config;
2. the enclave code will listen on the vsock port 6050 for forwarding the logging information;
3. the enclave code will use the INFO log level.

This may be confusing to node operators who may expect the enclave code would follow their configuration provided in the helper code on their host (in the toml configuration or from command line arguments).
