[Feature] Support Dulwich >=1.2.0 with an implementation for SSHVendor

[noel-nf]

Describe the bug
In an environment with airflow-dbt-python==3.5.0 and dulwich==1.2.1 (latest versions at the time of writing this), dulwich no longer contains a contrib module and I get a ModuleNotFoundError:

ModuleNotFoundError: No module named 'dulwich.contrib'

Thanks for reporting this issue. Seems we could fix it by including the contrib module as a requirement. Will take a look now.

Nevermind: Dulwich just does not include contrib anymore, anywhere, not even with the paramiko extra: https://github.com/jelmer/dulwich/releases/tag/dulwich-1.2.0.

The solution would be to bundle the module ourselves, but I do not want to take in the maintenance load.

For the time being I will require dulwich<1.2.0.

[tomasfarias]

Okay, we now require dulwich<1.2.0 in master (will cut a release later today or tomorrow, as I'd like some small CI changes to ship too).

This is no longer a bug as we explicitly do not support dulwich>=1.2.0. I'll update this ticket to be a feature request to support dulwich>=1.2.0. Shouldn't be too hard to bundle our own SSHVendor using paramiko.
