MM-22784 Advanced logging config for audit (#15076)

Adds the advanced logging config for audit. Existing support for auditing to a single file remains for E0 and E10 licenses instances, and a new config item ExperimentalAuditSettings.AdvancedLoggingConfig is added that behaves like LogSettings.AdvancedLoggingConfig.

Supported destinations:

- file
- syslog (with out without TLS)
- raw TCP socket (with out without TLS)

ExperimentalAuditSettings.AdvancedLoggingConfig can contain a filespec to a config file, a database DSN, or JSON.
