Fix saml-assertion parsing in assume-role-with-saml (#3523)
* Retrieve SAML Attribute by Name instead of relying on order which is too fragile

* Handle case when SAML Attribute SessionDuration is not provided, as it is not a required attribute from SAML response

When session duration not provided, AWS consider by default a duration of one hour as cited in the following documentation:
"If this attribute is not present, then the credential last for one hour (the default value of the DurationSeconds parameter of the AssumeRoleWithSAML API)."
https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_saml_assertions.html#saml_role-session-duration

Traceback was:

TypeError: __init__() missing 1 required positional argument: 'duration'

* Process saml xml namespaces properly instead of relying on textual prefix that can vary between identity providers

* Handle when SAML response AttributeValue xml tag contains attributes that force xmltodict to build a dictionary as for complex types instead of directly returning string value

Leverage force_cdata option of xmltodict parser that always return a complex dictionary even if xml tag contains only text and no attributes.

* Improve existing test_assume_role_with_saml to be coherent with other assume_role_with_saml tests and remove dead code at the same time
