Consider moving to a single workspace

[jbesraa]

Currently roles and protocols are separated and we have two workspaces in addition to common and other utils packages scattered around in the root folder. After we have completed #994 I suggest to do the next step, combining the protocols/roles/common into a single workspace and rename each one to have a stratum prefix, i.e., stratum-protocols and so on.

My undestanding was that we were ok in put roles and protocols in different git repos (we disscussed it in a call if I remeber correctly) why now you want to put them in the same workspace? Common can fo with protocols I guess
