feat(logs): support for capture_* config

[solnic]

This adds support for configuring the log handler error capturing - which is different from sending error logs and crashes.

Two new options are added go :logs config:

• capture_log_messages - toggle capturing on / off
• capture_level - the log level for capturing (distinct from logs.level config)
• capture_metadata - which metadata is accepted when capturing log messages
• capture_excluded_domains - which logging domains must be excluded when capturing log messages

This is the first step towards deprecating the original Sentry.LoggerBackend as Sentry.LoggerHandler is replacing it, handling both structured logging and capturing logs as Sentry events.

@PJUllrich would that be a good solution in your case? 😄

[PJUllrich]

@solnic yes, I think so! Thank you! ❤️💚💛💜💙❤️

Capture level filters crash reports

Medium Severity

The auto-attached handler always sets its level from logs.capture_level, and ErrorBackend drops any log event below that threshold before crash handling runs. That means a capture_level above typical crash severities (e.g. :critical) can suppress crash reporting, even when capture_log_messages is false or the docs describe crashes as always on and capture_level as applying only to captured log messages.

Restart resets handler options

Medium Severity

When the auto :sentry_log_handler survives a :sentry restart, re-sync calls :logger.update_handler_config/3 with only the four capture-related keys. Sentry.LoggerHandler.changing_config/3 validates that map through the full NimbleOptions schema, so omitted options are filled with defaults and overwrite existing handler settings such as :rate_limiting, :sync_threshold, and :tags_from_metadata.
