use latest java edot snapshot for ad & fraud services

[SylvainJuge]

Changes in sonatype OSS repository for snapshots implies that the redirect URL we are using to get the latest version of EDOT is no longer working and returns an obsolete snapshot version.

There is no direct replacement available, and we have to replicate the same snapshot resolution logic as maven using the available metadata descriptors in XML before being able to download the EDOT jar file.

Tested locally, the ad service shows the 1.5.1-SNAPSHOT version when starting, which means it is running with the latest snapshot available (was 1.4.2-SNAPSHOT previously):

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/src/app/opentelemetry-javaagent.jar
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
