I need to set a boolean value using --extraMetadata, however it seems that this option only supports strings, therefore something like:

--extraMetadata.updates.enabled=false

Results in:

{
    "updates": {
        "enabled": "false"
    }
}

I haven't tested it, but I suspect the same issue applies to numbers.

Of course I can workaround this limitation from my application code, however I wonder if we could add support for values other than strings.

Some thoughts:

• We could check if the value equals false, true, or contains only numbers and coerce appropriately, however there might be cases where you really need to set something like "false"
• Maybe there can be --extraMetadataBoolean and --extraMetadataNumber options?
