Olivier Lemasle 9a13227a78 CLOUDSTACK-10327: Do not invalidate the session when an API command is not available (#2498)
CloudStack SSO (using security.singlesignon.key) does not work anymore with CloudStack 4.11, since commit 9988c26, which introduced a regression due to a refactoring: every API request that is not "validated" generates the same error (401 - Unauthorized) and invalidates the session.

However, CloudStack UI executes a call to listConfigurations in method bypassLoginCheck. A non-admin user does not have the permissions to execute this request, which causes an error 401:

{"listconfigurationsresponse":{"uuidList":[],"errorcode":401,"errortext":"unable to verify user credentials and/or request signature"}}
The session (already created by SSO) is then invalidated and the user cannot access to CloudStack UI (error "Session Expired").

Before 9988c26 (up to CloudStack 4.10), an error 432 was returned (and ignored):

{"errorresponse":{"uuidList":[],"errorcode":432,"cserrorcode":9999,"errortext":"The user is not allowed to request the API command or the API command does not exist"}}
Even if the call to listConfigurations was removed, another call to listIdps also lead to an error 401 for user accounts if the SAML plugin is not enabled.

This pull request aims to fix the SSO issue, by restoring errors 432 (instead of 401 + invalidate session) for commands not available. However, if an API command is explicitly denied using ACLs or if the session key is incorrect, it still generates an error 401 and invalidates the session.
