dev: Use bollard to build local docker image in tests

[akhercha]

Current Behavior

We currently use CLI commands to build our local docker image for our tests:

let output = Command::new(DOCKER_BINARY)
            .args([
                "buildx",
                "build",
                "--file",
                self.dockerfile.to_str().unwrap(),
                "--force-rm",
                "--tag",
                &self.build_name,
                "..",
            ])
            .output()

Expected Behavior

We switch to using the bollard crate.

For example, see:
https://github.com/fussybeaver/bollard/blob/master/examples/build.rs

Why -> code robustness and maintainability. We'll have a better Rust integration, type safety, and error handling compared to CLI commands.

Also, bollard is actually used by test-containers-rs.

Alternative

Maybe it's cool to dig more the testcontainer-rs crate and contribute with an ImageBuilder struct or something. They also use bollard under the hood.
