Migrate authentication subsystem to the new platform. (#39446)

* Temporary Core workarounds.

* Move files to NP Security Plugin.

* Fix references.

* Migrate to the New Platform.

* Review#1: remove unused `loginAttempt` from provider iterator, rely more on RecursiveReadonly, etc.

* Integrate latest core changes: isTlsEnabled and get rid of legacy ES config.

* Revert `deepFreeze` changes and rely on `src/core/utils`.

* Review#2: do not mutate injectedVars in onInit. Integrate latest upstream changes.

* Use mocks provided by the Core.

* Expect ElasticsearchError instead of Boom errors as 401 Cluster client errors.

* Simplify session handling for `login`.

* Review#3: properly handle session updates for `login`, remove redundant hapi-auth-cookie deps from x-pack package.json, migrate to new core sessionStorage API, integrate latest Kerberos provider changes from upstream

* Do not clear session on login if it does not exist.
