Add possibility to set properties for each item

[garagatyi]

I'm using iterator plugin in Eclipse Che project https://github.com/eclipse/che-lib/blob/master/websocket-terminal/pom.xml

I need to build golang application for different architectures. It requires environment variable. I use maven exec plugin and would want to make pom more pretty with iterator plugin. But it is not possible to set these variables because I can't set properties for each item.
It would be really useful if iterator plugin supports such configuration:

<items>
    <item>
        <value>linux_amd64</value>
        <properties>
            <goos>linux</goos>
            <goarch>amd64</goarch>
        </properties>
    </item>
    <item>
        <value>linux_arm7</value>
        <properties>
            <goos>linux</goos>
            <goarch>arm</goarch>
            <goarm>7</goarm>
        </properties>
    </item>
</items>

Can you take a look with the current state and check if it works for you?

It works like a charm! Thank you a lot! I've just submitted a PR with usage of new syntax eclipse-che/che-lib/pull/7

I think it's time to make it available via Maven Central...WDYT ?

[khmarbaise]

Release to Central done. Take some time to synchronize...
