Converge dependency versions

[NiccoMlt]

Closes #476

• upgrade Maven Wrapper to Maven 3.9.9;
• add Reactor Tools to improve debug capabilities;
• upgrade Reactor Netty BOM to version 2023.0.11;
  • this bumps Project Reactor dependencies to 3.6.11
  • this bumps Reactor Netty dependencies to 1.1.23;
• use Netty BOM to ensure that Netty-related dependencies outside of Reactor Netty BOM are aligned to version 4.1.114.Final;
  • this includes io.netty:netty-tcnative-boringssl-static, now on version 2.0.66.Final;
• update acme4j to version 3.4.0;
  • this was a major update that required some small fixes because of some breaking changes;
  • only acme4j-client was kept, acme4j-utils doesn't exist anymore, see https://shredzone.org/maven/acme4j/migration.html for details;
• update Bouncy Castle to version 1.78.1;
• update Apache BookKeeper used by HerdDB to version 4.14.8;
  • we can't bump it any further without messing with HerdDB
• update Apache ZooKeeper to version 3.8.4;
  • this was required to drop safely the dependency to log4j 1.2, which we previously excluded from the dependency tree without actually being sure that logs were routed correctly to Java logger;
• introduce BOM for Prometheus Java client library to version 0.16.0;
  • we probably could have done a step forward here, using the Simpleclient Bridge with the Prometheus Java Client 1.0.0, but I think we need a dedicated issue to revamp Carapace metrics;
• consolidate versions of various Apache Commons libraries, that mostly come as transitive dependencies:
  • bump Apache Commons Codec to version 1.15;
  • bump Apache Commons Lang to version 3.12.0;
  • bump Apache Commons Logging to version 1.2;
  • bump Apache Commons IO to version 2.14.0;
  • drop Apache Commons Pool 2.11.1 that was never used;
  • bump Apache Commons Net to version 3.11.0
• introduce Eclipse Jetty BOM to consolidate dependencies to version 9.4.52.v20230823;
• introduce Eclipse Jersey BOM to consolidate dependencies to version 2.35;
• introduce Jackson BOM to consolidate dependencies to version 2.14.3;
• drop unnecessary, explicit, dependency to JAX-B;
• consolidate SLF4J dependency to version 1.7.35;
  • the backend of choice remains slf4j-jdk14, excluding transitive dependency to Logback;
• introduce Google Guava BOM to consolidate dependency to version 33.3.1 for JRE;
• consolidate Google Protobuf version to 3.17.1;
• upgrade Wiremock to version 2.35.2
  • waiting for Upgrade to WireMock 3 #485 for a major bump
• drop explicit Mockito as it conflicts with the version that comes with Powermock (see https://github.com/powermock/powermock/wiki/Mockito)
• consolidate Objenesis dependency version to 3.0.1;
• upgrade built-in Maven plugins to the latest versions;
• exclude transitive dependencies to unused annotations;
• enforce dependency consistence through Apache Maven Enforcer Plugin
