CLI - new-procedure command

[Latrasis]

We need a new-procedure command for setting up a new procedure code.

New-Procedure Command

Parameters:

• <name> - Name of new procedure

Output:

• Creates of new cargo project with the procedure name
• Creates a caps.json file with sample log capability
• Creates a sample main.rs file that uses the log capability to output "Hello World"

Deploy-Procedure Command

The deploy-procedure command is amended:

• If it just recieves the procedure name, it looks for a cargo project with the same name
• If it receives additional paths, it uses them instead

This all works in #191. That is:

• The user creates a new project via cap9-cli new <project-name> --acl.
• The user changes to the project directory.
• The user deploys the project with cap9-cli deploy.
• The user creates a new procedure with cap9-cli new-procedure <proc-name>.
• The user changes to the new procedure director called <proc-name>.
• The user builds the project via cargo build --target wasm32-unknown-unknown.
• The user returns to the project directory.
• The user deploys the procedure via cap9-cli deploy-procedure <proc-name>.
• The user verifies this deployment by running cap9-cli fetch procedures and seeing a procedure with the name <proc-name> is now in the procedure list.

I'm going to add some better error messages and tests.

Added error messages that should cover most if not all problems that might occur in this workflow and offer guidance on how to fix it.

Added execution of arbitrary procedures via the admin procedure. Added tests to execute new procedures via this process.

I added a script to the root of the cap9-cli package to step through all of these things with the right commands. I've reproduced it here:

cargo run --bin cap9-cli -- new --acl new-project
cd new-project
cargo run --bin cap9-cli -- deploy
cargo run --bin cap9-cli -- new-procedure hello_world
cd hello_world
cargo build --target wasm32-unknown-unknown --release
cd ..
cargo run --bin cap9-cli -- deploy-procedure hello_world
cargo run --bin cap9-cli -- fetch all-logs
cargo run --bin cap9-cli -- call-any hello_world say_hello
cargo run --bin cap9-cli -- fetch all-logs

This issue is completed with #191.
