When building PMM components or artifacts using docker, the volume mounts have proven to be efficient in speeding up the builds and saving on the network traffic. However, their use is inconsistent. We want to see a consistent use of volume mounts covering the following:

• go module cache

• go build cache

• yarn cache (UI components)

• dnf cache (packages)

A good example of using the mounts (tested) can be found in https://github.com/percona/pmm/pull/3299/files#diff-f24594f1d98096ba871dd0174562d39c84c9503315ef5bcfcb34f35059342182R141-R145
