feat: Cut SMF record about mapping OIDC token to mainframe credentials

[pavel-jares-bcm]

Description

This PR allows cutting SMF record during the processing OIDC token. It a token is mapped to an identity the SMF record could be cut. It contains the mapped user and the source user. Because there is a possibility mapping OIDC token by other than sub properties the use can define a different properties to be logged. So the SMF records contains mapped user an a source user.

The feature is as default disabled to mitigate a performance impact.

The new configuration properties:

apiml.security.rauditx.onOidcUserIsMapped

• Enable cutting SMF record on mapping distributed user from OIDC token to mainframe one.

apiml.security.rauditx.oidcSourceUserPaths

• Comma separated JSON paths to find source user in the OIDC token to be cut in the SMF record.
