Autologin Titan user into webmail

To auto login the Titan user into webmail, redirect to Titan webmail with these query params:

• webmailAutoLoginToken as slt (You will receive this token in the response whenever you create an email account)
• created email as email_account
• true as clearSession (This is optional. Add parameter in case the expectation is to log out any existing logged in accounts on webmail)

Example: https://app.titan.email/?slt=1:nkLjBJX9Uqgy&email_account=james@xyz.com

Note: webmailAutoLoginToken is a short lived token which is meant to be used immediately in the flow after creating an email account. This token should not be persisted and can't be used later to auto login into webmail.
