Rsync tls toomanyfiles

Describe what this PR does

Fixes rsync-tls issue with argments too long when many files are in the root of the source PVC

Is there anything that requires special attention?

• Made a copy of all files into /tmp/filelist.txt and then pass that as --files-from arg to rsync
• Needed to add -r flag to rsync (this flag is normally implied by -a, but gets turned off by default when using --files-from)
• added e2e tests that create 21k files
  • used long names to reduce the number of files needed to create the issue. Hopefully this doesn't cause perf issues with the actual e2e tests in CI. In my own env the sync does take a lot longer, but the compare pvc checks actually were surprisingly fast.
  • Also added some files on the source with subdirs and files/dirs that start with .
