Updated docker-compose.yaml to fix rpc bug

[Mansoor-AR]

In order to unlock accounts with Seth-rpc, the rpc service and the cli-go service need to share a volume where the aliases are stored. This PR introduces that volume.

I think you are missing the sign-offs in your commit message. You can fix it by running

$ git commit -s --amend

While you are there, please add some more context to your commit message, following this guide for writing commit messages: https://chris.beams.io/posts/git-commit/

After you've done this, force push your branch.

Can you add more context to the commit message itself? "In order to unlock accounts with Seth-rpc, the rpc service and the cli-go service need to share a volume where the aliases are stored. This PR introduces that volume." would work.

LGTM

This PR cannot be merged because the commit doesn't pass the DCO check (see comment from Apr 25, 2019) and we have a request to update the commit message (see comment from Jan 4, 2019). AFAIK these are the only things holding up this PR.

@Mansoor-AR I see 3 commits in place of one for this change. One option could be to cherry-pick the commit with DCO and then force push to the same branch name.

This repository will be archived soon so I'm closing this PR. Thanks for your contribution!
