Add new vendor's ssh code

[Yukissss]

Hi there,

I've added support for a new vendor, Asterfusion, by including the AsterfusionSSH class in our repository. Here's a summary of the updates and tests I've conducted:

New Class Addition:

Integrated the AsterfusionSSH class to enable connections and interactions with Asterfusion devices.
Testing:

All tests as outlined in the project's contribution guidelines have been performed.
Two tests encountered issues:
test_find_cfg_file failed due to directory path discrepancies on Windows. I've noted this down for further investigation.
Tests requiring genie and pyats could not be completed as these packages failed to install despite my attempts.

Thank you for considering this PR. I'm eager to contribute to the project and improve our support for Asterfusion devices.

Tests:

@Yukissss Okay looks like you have some type hint failures (see linter test failure above).

Could you update the PR and correct this?

[Yukissss]

Sure, I'll correct it when I have some free time:)

I've corrected this type hint failure, and I checked it by running poetry run mypy ./netmiko. The linter check should pass then :)
