Using the CertAuthenticator() for authentication does not work in 3.x

Using the CertAuthenticator() for authentication does not work in the 3.x Python SDK.

There are multiple of issues:

• The necessary connection string params (keypath, truststorepath) are not translated to the connection string correctly

  • Although the certpath param is added to the connection string

• If using a CertAuthenticator for authentication, the authentication for the Admin connection is incorrect

• If using a CertAuthenticator for authentication, authenticating the bucket connection is incorrect

There looks to be a decent amount of (unnecessary?) complication added to the authentication process from the tickets below. It seems it might be related to the 2.x RFC.

• PYCBC-487

• PYCBC-488

• PYCBC-489

NOTE: There seems to be enough effort to correct this to prevent this correct in the 3.x version of the SDK. Will assess a bit more, but current though is that the 4.0 will allow for the use of the CertAuthenticator().
