feat(chips): allow to specify md-max-chips attribute through md-contacts

[kylekatarnls]

Hi,

We would need for a limit of the number of contacts. Could we pass the md-max-chips options from md-contacts to md-chips the same way than other options?

Sub-question: could it be tagged as a patch version?

Thanks,
