fixing boolean flag in deployment args to be on a single line (#457)

Issue #, if available:
N/A

Description of changes:
Fixing deployment `args` to have boolean values on a single line. This is needed since the presence of the flag itself is a `truthy` statement, and the next line for the `env` is ignored. See [this](#455 (comment)) comment on `leader-elect` PR for more info.
