Ceph-RGW: Support rotation of s3 key pairs

This updates the helm-toolkit script for creating rgw s3 users
to first check if a user exists, then create the user if it does
not exist or modify the user's keys if it does exist. This is
accomplished by using jq to identify all existing access keys for
the specified user, removing those key pairs using the access key,
then modifies the existing user with the supplied access/secret
key pair for the given user

This also updates the ceph-rgw chart to use the helm-toolkit s3
user script for creating the admin s3 user instead of using a
similar script defined directly in the ceph-rgw chart
