Grant server read/write permissions on shared data path "path.shared_data".

Grant server read/write permissions on missing shared data path "path.shared_data".
This setting is deprecated, but possibly still used. This surfaced when enabling entitlements in internalClusterTest.

Relates to ES-12447

Hi @mosche, I've created a changelog YAML for you.

LGTM

Can you also check there is a qa test that actually uses shared data, so that we are sure the permission granted to server is sufficient?

[mosche]

There's lots of internalClusterTests using it, that's how i noticed this is missing. No QA rest tests though.
I tried testing locally, but couldn't figure out how this get's used and there's not much docs around it.
Happy to write a QA test if you could provide some pointers.

A rest test (java or yaml, doesn't matter) would be good as that is more realistic than an internalClusterTest. But if there are some tests already it doesn't need to block this PR, adding additional testing could be a followup.
