Add integration tests

[radumarias]

Add integration tests to access the FUSE endpoint and test all kind of operations.

Setup tests similar to examples/mount.rs and then run integration tests over the mounted folder.

To perform the actual operations use the std::fs::OpenOptions, std::fs::File, std::fs and std::io. All tests run against the mount-point.

Each test needs to have it's own mount-point and data-dir so they can be ran in parallel.

Add target guard to only run tests on linux for now until we have implementations of FUSE on macos and windows too. You can add this in tests, setup and teardown methods
#[cfg(not(target_os = "linux"))] { return; }

Reference unit tests you can combine logic from and adapt to integration tests

• src/encryptedfs/test.rs
• src/crypto/read/test.rs
• src/crypto/write/test.rs

Get from these too when done

• https://github.com/radumarias/rencfs/issues/117
• https://github.com/radumarias/rencfs/issues/58

You can also create similar tests like https://github.com/radumarias/rencfs/issues/181

You can also create bash tests similar to https://github.com/radumarias/syncoxiders/tree/main/file-tree-merge/tests/scripts

Also add tests with concurrent operations over fs.
