Update from Spring Boot 3.1.x to >= 3.2.x

[dsmf]

As a product
I want to update Spring Boot version to >= 3.2.x
so that IRS works with the current Spring Boot version.

Hints / Details

• https://github.com/spring-projects/spring-boot/releases

• Updating to Spring Boot 3.2.x involves more than just updating the version number because Spring 3.2 dropped some classes:

  • RestTemplateExchangeTags
  • RestTemplateExchangeTagsProvider (in favor of ClientRequestObservationConvention
  • We use these classes in module irs-api o.e.t.irs.util.CustomUriTagProvider for providing a custom prometheus tag configuration for the request buckets because the default configuration includes the query string in the URI tag which leads to lots of metric entries for each different call.

• Maybe adding a new (integration) test is necessary, because there does not seem to be any test that would verify our custom Prometheus configuration yet.

Outcome / Acceptance Criteria

Acceptance Criteria

1. Update to Spring Boot version to 3.2.x
2. Find and implement solution for dropped classes (and prove in some way that the custom prometheus configuration is still working).
