Read only bind and volume mounts

[silh]

Added the ability to specify read-only bind and volume mounts.
That ability is present in docker client itself as well as in java version of testcontainers - see https://www.testcontainers.org/features/files/

Thanks for this contribution, it makes total sense.

I wonder whether directly merging it as a breaking change in next minor (we are still in 0.x.y) or include it in an eventual 1.0.0 release 🤔

@gianarb thoughts?

[silh]

I though about making it non breaking but less obvious - keeping the map[string]string but parsing the end of the value to contain :ro suffix. Wasn't sure weather that's a good approach to take.

[gianarb]

I would like to go with the :ro :rw parsing if possible! That syntax is stable since Docker showed up and I don't think it will change in the future 👍

Did it with :ro and `:rw: but while rebasing I saw that there was already breaking change which might create confusion with order of host path and container path in those maps and I think the structure would have been more clear.

[silh]

Is anything else needed?
I am not sure about the coverage drop in wait/http.go - it seems flacky.

[mdelapenya]

Can you double check if there are incompatible changes with #386?

[silh]

I think #386 make this PR obsolete and it can be closed.
There is already a way there to specify if you want a readonly container.

[mdelapenya]

Closed as per @silh's comment. Thanks you very much for your time with testcontainers-go!
