Create quarkus-sentry Extension

[ia3andy]

Description
This extension would add sentry support, the idea would be that when the sentry extension is enabled, you configure quarkus.sentry.dsn and you are done.

Implementation ideas
Here are some leads to implement it provided by @dmlloyd:

basically logging is configured in io.quarkus.deployment.logging.LoggingResourceProcessor
the configuration is held in io.quarkus.runtime.logging.LogConfig and its members
in order to add Sentry support, we'd need to do one of two possible things
one would be to add a Sentry extension which adds a new configuration root, for example LogSentryConfig, and then has configuration options similar to the existing ConsoleConfig, FileConfig, etc.
then it would have a processor which produces a new build item that would be added to the core module, for example LogHandlerBuildItem, which the LoggingResourceProcessor would consume to complete the handler setup
so that's option one
option two would be to add a generic handler config to LogConfig
something like Map<String, CustomHandler> customHandlers; with a CustomHandler class that includes a class name and some generic way to set up the custom handler

This would solve #2409

In the meantime, something like this could help: #1847
Additionally registering SentryHandler and configuring the ConsoleHandler with PatternFormatter as is done in

quarkus/core/runtime/src/main/java/io/quarkus/runtime/logging/InitialConfigurator.java

Line 46 in 6cb8707

ConsoleHandler handler = new ConsoleHandler(new PatternFormatter("%d{HH:mm:ss,SSS} %-5p [%c{3.}] %s%e%n"));

Edit: maybe you can even get away with InitialConfigurator.DELAYED_HANDLER.addHandler(new SentryHandler()) instead.
