Proposal: All Contributors to have a signed Apache ICLA

Hi All

I'd like to suggest that we implement a policy that all project contributors
of ideas, code and documentation (so this includes people updating the wiki)
to have signed Individual Contributor Licence Agreements (ICLA)

*What it means?*
Signing an ICLA means that you understand that what you have contributed (or
want to contribute) is subject to the Apache Licence and that you are happy
to do this.

The ICLA is not tied to any employer you may have.

Details of the Apache Licences and Contributor Licence Agreements can be
found at the link below:

Future Contributor Process*
The future process could be as follows:

1. Anyone requesting to become a contributor will need to have completed an
ICLA
2. We will check the official list of filed ICLAs before granting
contributor permissions (e.g. on the wiki)

If the community is happy to implement this policy then I will

1. Take a look at our current list of wiki contributors and see if any do
not have an ICLA on file
2. Contact them with the details of how to file one

Thanks
Sharan
