Add ark-cli crate

[tareknaser]

This pull request adds the ark-cli crate into the ark-rust workspace.

Changes made:

Relocated all ark-cli code into a new crate.

Note: A git merge conflict occurred with the README file. I had to add a separate commit to add it.

Next steps

currently, ark-cli still depends on ark-lib

arklib = { git = "https://github.com/ARK-Builders/arklib", rev = "2c7ceda" }

We should make it depend on other crates from the workspace

Follow-up:

• ark-cli: Refactor to depend on crates from ark-rust not arklib #15

[tareknaser]

Ok so I refactored the PR

Changes Made:

• Used git filter-repo to rewrite each commit of ark-cli under the ark-cli/ directory (documentation reference).
• Merged the new git history of ark-cli into ark-rust (allowing unrelated histories).

Advantages:

• Preserved the original git history of ark-cli. Authors and commit dates are correct
• Examining commits from ark-cli doesn't show "This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository" message

Disadvantages:

• All ark-cli commits are rewritten so they are basically not the same. They don't have the same commit hashes

To justify 231a6ce:

Currently, ark-cli depends on arklib at a specific commit "2c7ceda" https://github.com/ARK-Builders/ark-cli/blob/main/Cargo.toml#L11. This commit of arklib relies on "image v0.24.2". Due to a compilation issue, we made changes in ARK-Builders/arklib#87 , shifting to "image v0.25". This change was included in ark-rust as well.

ark-rust now depends on "image v0.25". The current setup poses a compatibility issue because ark-cli relies on arklib, not other crates in ark-rust. We are planning to address this issue in #15

As a hot fix, I made a new branch https://github.com/ARK-Builders/arklib/tree/ark-rust_hot_fix aligning with the same commit as ark-cli, with an additional commit to resolve the compilation issue.

@tareknaser good work, I think solution using git filter-repo is OK. Commit hashes don't have to be exactly the same as in the older repo. The most important is preserving authorship and dates.

Glad to see this pull request merged!

I've merged the PR. The commits in ark-cli retained their original authors and no longer display the "This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository" message as expected.
But it seems that the commit dates in ark-cli have been reset to today's date.

After second thought, it makes sense because ark-cli and ark-rust have unrelated git histories. To maintain the git histories of both repositories, we would need to rewrite the git history of ark-rust from scratch as well.

@kirillt What's your take on the current approach? Are you content with it, or do you lean towards rewriting the git history of ark-rust?
