Activate `use-apache-snapshots` profile

[ppkarwasz]

As documented on the ASF Parent POM website, since version 34 the ASF Parent POM moves the apache.snapshots repository to the use-apache-snapshots profile.

We have two choices here:

• We can activate the profile in the parent POM and work as usual.
• We can activate the profile only in the builds that actually need it (e.g. logging-log4j-samples

@vy: what do you think?

Ugh! This hurts. Thanks for spotting this @ppkarwasz!

the pom adds the Apache snapshot repository (https://repository.apache.org/snapshots) This only happens if the apache.snapshots property is set, or the use-apache-snapshots profile is active.

I guess we can also use the shared property too.

We can activate the profile only in the builds that actually need it (e.g. logging-log4j-samples)

I'd be in favor of this approach. Expose it wherever it is needed.

For now I did it in apache/logging-log4j-samples#306 and I think it is the only repo that requires it.

On the other hand there is a small problem during development: if you work let us say on log4j-core and you want to download log4j-api from our Snapshots, you need to run:

mvn <something> -pl log4j-core -Puse-apache-snapshots

or use a local build instead and make a mvn install before.
