+++ This bug was initially created as a clone of Bug #2062007 +++

Description of problem:

The `machine-config-controller bootstrap` subcommand uses the `--template` flag default value, but the flag is only associated with the `start` subcommand internally, so end users can't actually override the hard-coded default value when running the `bootstrap` command.

Version-Release number of MCO (Machine Config Operator) (if applicable):

Platform (AWS, VSphere, Metal, etc.): All
