[Portal] Adjust Pods Requests/Limits

[Portal] Adjust Pods Requests/Limits

I've adjusted the Requests / Limits of portal pods according to real
usage of "Orange Openlab" and "Onap daily master".

Calculation is the following:

per deployment:
 * CPU/Mem requests is max of average from the two deployments
 * CPU/Mem limits is (max of max from the two deployments) * 1.2

 Moved portal-widget CPU limit to 1 as it's not starting if set to lower
 than that.

 Full values are available on jira ticket
 (https://jira.onap.org/browse/PORTAL-517).
