Use real memory circuit breaker when running Elasticsearch from source

[iverase]

During development I often run elasticsearch from source using ./gradlew run. While working with the real real memory circuit breaker I noticed that it is disable when running in this mode and it is not allow to use it:

Execution failed for task ':run'.
> Testclusters does not allow the following settings to be changed:[indices.breaker.total.use_real_memory] for node{::runTask-0}

The issue is the following line and commenting it out makes the clsuter work with the circuit breaker:

elasticsearch/build-tools/src/main/java/org/elasticsearch/gradle/testclusters/ElasticsearchNode.java

Line 1421 in da389b4

baseConfig.put("indices.breaker.total.use_real_memory", "false");

I am wondering if we can revise this restriction and if it is obsolete, allow to run test clusters with the real memory circuit breaker.

This was originally set as part of #31986, due to limitations in clients

@elastic/clients-team is the restriction in

elasticsearch/build-tools/src/main/java/org/elasticsearch/gradle/testclusters/ElasticsearchNode.java

Line 1426 in 6c17798

// Temporarily disable the real memory usage circuit breaker. It depends on real memory usage which we have no full control

still applicable?
