Init Template Option

[lukacan]

As we are no longer using skip_fuzzer option. It would be helpful to provide the option to generate only the desired test template (for example PoC tests do not need dependencies used for fuzzing).

This PR contains trdelnik init template option:
both - generates templates for both types of tests (+ program_client) [default option]
poc - generates template for PoC tests (+ program_client)
fuzz - generates template for fuzz tests (+ program_client)

UPDATE!

After the internal discussion, I propose the following changes and updates:

• trdelnik init contains subcommands for "Both", "PoC", "Fuzz" Tests option, to generate only desired Test Folder/Template

  • Both - generates program_client, fuzz_tests folder and also poc_tests folder with all required subfolders
  • PoC - same as Both but does not generate fuzz_tests folder
  • Fuzz - generates only trdelnik-tests/fuzz_tests folder with all required subfolders
    • .program_client is not required for fuzz tests so program_client is not generated
  • Trdelnik.toml is generated with all cases
  • Worskapce manifest is updated accordingly for PoC/Fuzz tests (this was not modified - only informational)
  • .gitignore is accordingly updated for hfuzz_target - only in case of Fuzz Tests (this was not modified - only informational)

• Additional changes and updates

• Build command and Init Command were updated to look for the root directory - this was done previously within the TestGenerator, and the root folder path was sent into all of the used TestGenerator functions. Now within Build,Init and Fuzz(in case of Add) the root is obtained right after the command invocation, and then TestGenerator is created with the root which is then used everywhere required.

• Similar to the previous point, the Init command right after invocation checks for Anchor.toml/Cargo.toml based on the desired option. For example, for Fuzz Tests we only support projects created by Anchor so it will look for Anchor.

• In terms of TestGenerator and Commander modules. The logic remains the same however some parts were moved from Commander to the TestGenerator. For Example, creating a program_client crate should be located within the TestGenerator as this is the module where all other files are generated.

• In terms of fuzz tests. As we do not require to generate program_client, the default file content of fuzz_test.rs was modified to obtain PROGRAM_ID right from the program not from the program_client.

  • Cargo.toml template for Fuzz Tests no longer contains dep for program_client

  TODO: some rustdoc comments would be great

I apologize for updating under your hands. The updates are only rebase develop for the latest PR and the build command will not run if Trdelnik is not initialized - Trdelnik.toml not present.

It looks good, only please change the details below...
