added stacktraces for queries

[dmecke]

I've added a stacktrace to the query profiler. This can help to find out why a specific query has been executed. This one depends on pull request doctrine/dbal#535 in doctrine/dbal as it fetches the stacktrace information.

I don't really see the need of using a separate action to do the rendering of the trace, whcih is just rendering of data stored in the profile.

a separate action is used to render the query explanation, because it requires explaining the query first. IT is not the case here

closing as the DBAL PR has been rejected

Just for reference, this feature is already available in Doctrine bundle from v1.11.0: https://symfony.com/blog/new-in-doctrinebundle-1-11-0#store-backtraces-when-profiling-queries (PR: #954) .

You just need to enable it by setting doctrine.dbal.profiling_collect_backtrace: true (I set it to '%kernel.debug%' instead because it is the default value of profiling setting).

Web search got me here and from this conversation it looks like it may not be available yet.

Well, this conversation is from 2015. There are other PRs newer than that.
