* Adding in SCP options configuration
This changeset adds in additional SCP options to the config. This allows
the user to specify a list of flags to send to the SCP command that will
be expanded into each shell command.
The primary driver for this is from newe boxes SSHing into pre 9 openSSH
boxes. New openSSH uses sftp server under the hood, rather than the
older SCP protocol. If you go into a system that does not have these
changes, SCP fails to work. The '-O' command line flag was introduced to
resolve this.
Using this change, the user can now pass in `extra_scp_options = {"-O"}`
to resolve the issue.
* Replacing table.unpack with global unpack
* lint: apply stylua
* refactor: change option name and shuffle config around
