Support for BitBucket HTTPS Token due to SSO/SAML authentication restrictions

[raffertyuy]

Description

We need a way to migrate from BitBucket with SAML Authentication enabled. We believe this can be solved by supporting BitBucket HTTPS token which gh bb2sgh doesn't support.

(Unauthorized): {"errors":[{"context":null,"message":"Authentication failed. Please check your credentials and try again.","exceptionName":"com.resolution.atlasplugins.samlsso.bitbucket.userauth.OnlySAMLAuthenticationAllowedException"}]}

@raffertyuy My understanding is that the export API that bbs2gh uses only supports usernames and passwords - so I'm not sure how we'd solve this.

Would you be willing to try calling this API manually with an HTTPS token? If we can prove that that works on an instance like yours with SAML enabled, then that could unlock supporting this feature.
