Features from optional dependencies

Managing dependencies on crates from starkware-libs/cairo repository:

The Cairo compiler is made of a bunch of crates that inter-depend on each other and have synchronised versioning. It is very important to use a single revision of these crates in the entire Cairo toolchain, which consists of Cairo compiler, Scarb, CairoLS and other tools. The toolchain is eventually built by Scarb, which depends on everything other as regular crates. To ensure that all crates in the toolchain use the same revision of Cairo crates, we use a patch mechanism that Cargo provides. Because Cargo requires patches to change the crate source, we have an unspoken contract that all tools always depend on some crates.io versions of Cairo crates and Scarb uses patch.crates.io table to set final git revision for everything.

To keep our Cargo.toml following this contract, always use cargo xtask upgrade for manipulating these dependencies.
