Subject: [PATCH] fix: allocate PTY for agent install to work with sudo
 requiretty

The remote server has 'Defaults requiretty' in sudoers, which prevents
sudo from running without a TTY. Modified SSHService::exec() to accept
an optional  parameter that allocates a pseudo-terminal, and
extracts the exit status from output when PTY is used (since phpseclib
doesn't return exit status in PTY mode).
