This commits consists of three major changes:
1. Support a new interface to get the base64 quote only.
This is useful in the case that application sends the quote
to service provider server and get the final IAS report there.
The application itself doesn't depend on IAS in this case.
2. Improve the C++ programming style. Now, we only provide
C++ classes and limited C APIs(for configuration and sgx device).
3. Use the more general keywords as names prefix.

1. Disable zlib _explictly_ when building libcurl in remote attestaion demo.
The reason for this is that zlib may be implictly linked by the build system of
libcurl but not the zlib library is not copied into the Occlum FS image.
2. Use `make -j$(nproc)`
3. Fix typos
This demo consists of
1. An user-friendly library for getting Intel Attestation Service (IAS) report.

This demo requires obtaining service provider certificate/ID from Intel.
