feat: options flag in dtn ssh

Description

This PR introduces support for the -o flag in the dtn ssh command, enabling users to supply SSH options in the KEY=VALUE format, similar to how native SSH handles it. This feature enhances the flexibility of the dtn ssh command by allowing users to pass multiple SSH options as needed.

Key points:

• Users can now provide SSH options in the KEY=VALUE format, just like with the native ssh command.
• This update supports both single and multiple options.

Examples:

• For multiple options:

  dtn ssh -o Compression=yes -o LogLevel=DEBUG

• For a single option:

  dtn ssh -o Compression=yes

Checklist:

• This change requires a documentation update.
• I have made corresponding changes to the documentation.
