py-asyncssh: updated to 2.7.0

Release 2.7.0 (19 Jun 2021)

Added support for the ProxyCommand config file option and a corresponding \ 
proxy_command argument in the SSH connection options, allowing a subprocess to \ 
be used to make the connection to the SSH server. When the config option is \ 
used, it should be fully compatible with OpenSSH percent expansion in the \ 
command to run.
Added support for accessing terminal information as properties in the \ 
SSHServerProcess class. As part of this change, both the environment and \ 
terminal modes are now available as read-only mappings. Thanks again to velavokr \ 
for suggesitng this and submitting a PR with a proposed version of the change.
Fixed terminal information passed to pty_requested() callback to properly \ 
reflect requested terminal type, size, and modes. Thanks go to velavokr for \ 
reporting this issue and proposing a fix.
Fixed an edge case where a connection object might not be cleaned up properly if \ 
the connection request was cancelled before it was fully established.
Fixed an issue where some unit tests weren’t properly closing connection \ 
objects before exiting.
