[torchx/cli] Fix mis-indented multi-line info log for `torchx run`

[kiukchung]

🐛 Bug

There are several cases that I've identified (there may be more) where the torchx run cli has some poorly aligned multi-line log messages. See screenshot below:

Module (check all that applies):

• torchx.spec
• torchx.component
• torchx.apps
• torchx.runtime
• torchx.cli
• torchx.schedulers
• torchx.pipelines
• torchx.aws
• torchx.examples
• other

To Reproduce

Steps to reproduce the behavior:

1. torchx run -s local_cwd --dryrun utils.echo
2. torchx run -s local_cwd utils.echo

Expected behavior

multi-line log messages should NOT be misaligned

Environment

N/A
