Allow reading the log via REST without superuser authorization (backport to 4.8) - #772

The REST endpoints GET /ws/rest/log and GET /ws/rest/log/size are already
guarded by fine-grained REST authorizations (authorization-rest-3#getLog
and #getLogSize). However, the underlying model operations
ModelDiagnosticService.getLogFileContent() and getLogFileSize() called
securityEnforcer.authorizeAll(), i.e. they required authorization-3#all.
The effect was that only a superuser could read the log, and the
fine-grained REST authorizations were unusable in practice: a read-only
administrator could not be granted access to the log at all.
This adds a new model authorization action
http://midpoint.evolveum.com/xml/ns/public/security/authorization-model-3#readLog
and uses it in ModelDiagController instead of authorizeAll(). This follows
the existing #readThreads pattern used for the thread dump operations, and
the note in ExtensionSchemaRestController about combining a specific REST
action with a specific model action instead of "all".
A single model action covers both the content and the size operations: the
size is strictly less information than the content, and clients are
expected to use them together (see the ReturnedDataPosition /
CurrentLogFileSize response headers). Deployments that want to expose only
one of the two endpoints can still do so via the REST-level authorizations.
The change is backward compatible: #all is applicable to any action, so
existing superusers are unaffected.
Also adds REST integration tests for both endpoints - they had no test
coverage at all - and documents the required authorization on the service
interface.
The other authorizeAll() call sites in ModelDiagController (memory
information, repository diagnostics, etc.) are deliberately left unchanged.

Backport of #769 to

ModelDiagnosticService: on mastergetLogFileContent/getLogFileSizealso throwSubscriptionComplianceException, which does not exist on this branch — resolved by keeping this branch's signatures and taking only the javadoc. Apart from that the added/removed lines are byte-identical to the master commit (same 10 files, +179 −4).Not built or tested on this branch locally; on master
