ocm toi bootstrap package should support specifying ocmconfig on the command line

[dee0sap]

What would you like to be added:

Here are the flags for ocm toi bootstrap package :

   --config stringToString   driver config (default [])
  -C, --create-env string       create local filesystem contract to call executor command locally
  -c, --credentials string      credentials file
  -h, --help                    help for package
      --lookup stringArray      repository name or spec for closure lookup fallback
  -o, --outputs string          output file/directory
  -p, --parameters string       parameter file
      --repo string             repository name or spec

While there is a --config flag it is for the driver, i.e. docker, and not for ocm itself. So to specify a config file you need to run ocm like so

HOME=/home/dsmall/git-repos/ocm-toi-helloworld/userInput ocm toi bootstrap package ...

With other commands you can use --config to specify the location of the ocmconfig.

I recommend that we add --ocmconfig for the location of the ocmconfig so that backwards combability is maintained

Why is this needed:

Because overriding HOME could have side effects.

Also, as it stand if the TOI installer requires credentials that are actually in a repository such as Vault, you need to provide both a credentials file and an ocmconfig file. You aren't able to just provide a credentials file. ( I'll create another ticket for this )
