rust: specify ring version

[ptrus]

Specify exact ring version in Cargo.toml as otherwise project depending on oasis-runtime (e.g. oasis-sdk), will need to manually lock ring to the exact version.

[kostko]

Makes sense. What's with all the updates in Cargo.lock?

[ptrus]

I updated Cargo.lock (via cargo update) as a test to ensure ring version will stay at the specified version.

I think now that oasis-runtime is also used as a library (in oasis-sdk) we should try keeping Cargo.lock up to date, since these are the versions of dependencies that a crate depending on oasis-runtime will use (unless overridden). E.g. before this change a crate depending on oasis-runtime#master would get ring 0.16.20 version which doesn't match the ring-sgx patch version - and having an up to date Cargo.lock would catch this sooner.

[kostko]

Ok. While doing this, we should also update the crate versions to something other than 0.3.0-alpha. Or maybe just remove the versions and expect downstream to use git tags?

[ptrus]

Hm yeah i think we should just remove the version for now?

[kostko]

Agreed, let's remove it.
