Change:
Allows the user to configure sshpass (1.06+) to look for a different
substring than the default "assword" that it comes with.
Test Plan:
Set a custom ssh password prompt on a VM with PAM and tried connecting to
it. Without `ansible_sshpass_prompt` set in inventory: experienced hang.
With `ansible_sshpass_prompt` in inventory: connected successfully.
Tried setting `ansible_sshpass_prompt` with an older `sshpass` in PATH
and got a loud error, as expected.
