What does this PR do?

This PR adds support for the --remote-repo-url flag to the iac test command. The flag can be used by a user to override the URL of the Git repository, that is otherwise auto-detected by the command.

Where should the reviewer start?

Most of the logic is in src/cli/commands/test/iac/scan.ts. The change in this PR creates an IacOutputMeta object at the beginning of the scan and passes it down to the components that need the information in it. Previously, the IacOutputMeta was constructed by the individual components, and surfaced up the stack. Because the IacOutputMeta is not dependent on the paths being scanned, it can be constructed once from a combination of flag values and auto-detected information (like the name of the current working directory and the URL of the Git repository, if any).

How should this be manually tested?

Use different combinations of current working directory and flags:

• If the current working directory is not a Git repository snyk iac test --report creates a project group whose name is the name of the current working directory.
• If the current working directory is a Git repository, snyk iac test --report creates a project group whose name is derived from the URL of the Git repository, in the same way as the examples below.
• snyk iac test --report --remote-repo-url=foo/bar creates a project group whose name is foo/bar.
• snyk iac test --report --remote-repo-url=https://example.com/foo/bar.git creates a project group whose name is foo/bar.
• snyk iac test --report --remote-repo-url=git@example.com:foo/bar.git creates a project group whose name is foo/bar.

The summary section will always return the correct project name. For example,

  Your test results are available at: https://dev.snyk.io/org/francescomari/projects
  under the name: foo/bar

we also discussed on slack to check that we do some sanitisation on registry side for the remote url string. So probably merging this after any registry changes.

Blocking as Hammer refrains from adding new dependencies to the CLI unless totally needed. We think it's not a must here, and would prefer no new dependency is introduced
