Do not add workspace logs volume in Che 7 workspaces

[garagatyi]

Description

Here is an example of volumes usage by a Che workpsace borrowed from this PR:

We use a single volume (or multiple volumes with the unique volumes provisioning strategy) to save logs of some agents.
But in Che7 workspaces produce logs as containers logs and this approach doesn't make much sense anymore.
In a case, logs need to be persisted this should be done on the infrastructure level and do not couple containers in a workspace.
