Add access to share for use with other add-ons

[sikaiser]

Proposed Changes

Add acces to the directories /media and /share, as originally requested in #133. According to this post in the community forum, these folders are intended for the sharing of files between (home assistant and) addons, so I think the addon should have access to them.

All 3 of /media, /ssl and /share were designed in part to be a place shared between Home Assistant and Addons so multiple things could read and write to it and potentially communicate with each other. /share was kind of the bucket for files which didn’t fit the obvious types of the other two (media in /media, ssl-related files in /ssl, everything else in /share).

The specific use case that brought me to this: I have an SQLite database file that I want to store locally and read in Grafana. I could put it in /homeassistant_config or /ssl, but conceptually it doesn't fit there. I'd much prefer having it in /share.

And why /media?

[sikaiser]

I thought to include it because it is also intended for access across addons. But I personally can not give you a concrete use case. /share solves my specific problem.

Right, but just adding it because we "can" is not something I'm a fan of. Everything we add adds more access to the add-on. Especially without a direct need or use-case for it, that is just unnecessary.

Let's remove media.

My suggestion to add it was because in my understanding it is intended for shared access, not because we "can". But I see your point and having access to /share alone is great too. I've updated the pull request.
