[SecurityBundle] Missing configuration reference (XML)

[carsonbot-test]

I found that there are some configuration missing for the SecurityBundle configuration reference page. This is a list of what is missing:

- security.enable_authenticator_manager
- security.access_decision_manager
- security.access_decision_manager.allow_if_all_abstain
- security.access_decision_manager.allow_if_equal_granted_denied
- security.encoder.hash_algorithm
- security.encoder.key_length
- security.encoder.ignore_case
- security.encoder.encode_as_base64
- security.firewall.request_matcher
- security.firewall.access_denied_handler
- security.firewall.entry_point
- security.rule.requires_channel
- security.rule.allow_if

Could someone please add these?
