feat: Add support for ignoring files using gitignore

[mellonnen]

If the --gitignore flag is supplied the behavior is:

• If a root git repository is supplied to portal send files in the repository will be ignored according to gitignore file
• All other cases (including folders in a git repository) will be sent regularly.
• .git folders are always sent

Example:

.
├── dir
│   └── file.txt
└── gitrepository
    ├── .gitignore
    ├── .git
    │   ├── HEAD
    │   ├── config
    │   ├── description
    │   ├── hooks
    │   ├── info
    │   ├── objects
    │   └── refs
    ├── main.go
    └── somedir
        └── file.go

# .gitignore
somedir/

• portal send gitrepository dir --gitignore would send

  • dir/file.txt
  • gitrepository/.gitignore
  • gitrepository/.git/
  • gitrepository/main.go

• portal send gitrepository/somedir --gitignire would send

  • gitrepository/somedir/file.go

The feature is implemented by issuing git shell commands, which reduces the complexity of writing a gitignore parser instead relying on the actual git ignore implementation. However, if we are to use this approach we would make sure to test it in other shells (other than bash and zsh) like (powershell and cmd etc).

Nice stuff. I think using the git client makes a lot of sense, but I do think we should double check that git is installed and reachable/usable in the system quite early when the flag is passed. One might be working on a git-folder in a remote computer/container that does not have git installed, and the error should be clear in that case.
