Pipelines Runner mounting host shared dirs

Currently, Runners doesn't support mounting host shared dirs in the Runner container.
When we run a command on Pipelines (e.g. creating a file inside the host shared dir), it won't work.

Alternatively, we can use SCP Deploy Pipe to upload files to the target host.
However, some target hosts aren't publicly available for security reasons.

Feature request:
It would be useful to support mounting host shared directories into Runners container.
