ReadWrite no longer a parameter for Persistent Storage.

http://www.projectatomic.io/blog/2016/01/atomic-app-0-3-1/ and docs need to be updated.

This will be fixed by #576 for the README.md, incoming PR for atomic-site.

Basically, we implemented persistent storage before kubernetes hit 1.0.0 and thus the API changed before release.

ReadWriteOnce, ReadOnlyMany, ReadWriteMany are the new options.

Do those names also work with Marathon? How do we interpret them for Docker?

Unfortunately just Kubernetes is supported at the moment :( the docs will be updated soon with the information about it.

[jberkus]

My point is, we shouldn't be using provider-specific names in Nulecule files.

ReadWriteOnce, ReadOnlyMany, ReadWriteMany these words seem to nail the desired behavior of the persistent volume pretty well, I would consider them as 'common sense and meaningful' rather than 'provider specific names'.

[jberkus]

Ok. In that case, though, we'll want to have plans for how those will map to other providers.

@cdrage - there are also several tests that mention 'ReadWrite':

./tests/units/persistent_storage/test_ps.py
./tests/units/persistent_storage/test_examples/ps-helloapache/Nulecule

Closing as #610 #611 has fixed this. Plus the update to the docs
