feat: ease of use debugging

[cyberhck]

When we want to use debug mode, we can only get 1 file per node in Kubernetes, this change allows us to do 2 things:

• set restartPolicy of pod as desired.
• add hostname in path for collecting healtrack data.

Fixes #5789

Thanks for your contribution, it's much appreciated.

If we make this change, it may be a little surprising to users, since their output heaptrack data files will now have a hostname in them. I don't think that's a big deal, since we aren't offering any guarantees about the stability of output debug file names. However, I would like this to be called out explicitly in the changelog.

Once you decide exactly which format of output file name to use, please update the changelog so that it has an example that illustrates the impact of the change.

@garypen does this look better? Sorry about the text in changeset, English is my second language. But if you suggest something, I'll use it.

@garypen not sure why CI is failing, anything I can do to help?

It's an issue relating to a test which won't work for external contributions. I'm going to merge your PR without waiting for the tests to pass. It's a change that won't impact any of our tests anyway...
