(BKR-1690) Rm -rf not working when path has spaces and logging on localhost

[genebean]

The information below is being transferred from Jira:

Problem 1:
Environment: beaker tests on remote windows machines.

Problem: When deleting folders with beaker method rm_rf which have spaces in their path, nothing happens.

This leads to leaking tests.

Problem 2:
When running tests using beaker on localhost (without provisioning an actual machine), we don't see the commands output with debug option enabled.
