Resolve "match new SSO field names"

Closes #4 (closed)

The sso.dsop.io time-based one time password login form were updated from totp to be otp. This was causing the replicator SSO logic to fail.

This update fixes the SSO logic allowing replicator to access the DCAR website.

This merge request is to update ...

• the name for the form id used to find the form post url
  • kc-totp-login-form -> kc-otp-login-form
• the form field
  • totp -> otp
• the unittest data html files used to unittest the SSO logic
