sgx

As described in #275, please help me with the documentation of SGX SDK:

• Move existing wiki into the /documents/ directory
• Write tutorial and tips of using SGX SDK to build SGX application
• Cleanup the /documents/ directory

This documents will be rendered in our homepage (https://teaclave.apache.org/sgx-sdk-docs/). Thank you so much!

Since raw queries only return encrypted keys, it's pointless and will break implementations coming from other networks without letting anyone know.

We should remove it from the next version

Describe the bug
The SGX enclave entry functions for Sonora are not easily discoverable

To Reproduce
Try grepping for sinaloa_init_remote_attestation_enc in the project directory. You will find calls to it but not an implementation

Expected behaviour
To aide newcomers to the project, functions should be easy for them to find the implementations of.
