[common] GPGcheck for RDO repository cannot be configured

[Imtiaz Chowdhury]

Currently, gpgcheck flag is not configurable and is always enabled by default. For certain use cases, for example, using these cookbooks in production where internet access is restricted, we need to disable
gpgcheck.

Users should be able to configure gpgcheck through a node attribute.

Proposed fix for this issue is under review [https://review.openstack.org/#/c/149895/]. We would like to see it applied to older releases, Icehouse and Juno, if possible.

    Making gpgcheck configurable for RDO repo

    Currently, gpgcheck flag is not configurable and is always enabled by
    default. For certain use cases, for example, using these cookbooks in
    production where internet access is restricted, we need to disable
    gpgcheck.

    This commit makes the gpgcheck configurable so that users can override
    it if needed.
