---
# Ensures a project exists and is configured in accordance with ICHP rules:
#
#   - has correct RBAC (user role binding)
#   - has network policies
#   - has quota and limitranges
#   - has an EgressIP allocated
#
# Requires the following structure:
#
#   role:
#     state:          present or absent
#     requester:      the user requesting the project
#     name:           the name of the project
#     displayname:    optional displayname (defaults to name)
#     rbac_level:     cluster role to assign to requester
#     egress_ip:      an available egress IP to allocate to the project
#     quota:          compute resourcequotas
#       requests:       compute reservation
#         cpu:            max cpu reserved (1500m, 1.5 CPU)
#         memory:         max memory reserved (2048Mi, 2Gi)
#       limits:         compute limits
#         cpu:            max cpu consumed (4000m, 4 CPUs)
#         memory:         max memory consumed (4096Mi, 4Gi)
#     lrange:         compute limitranges, for both container and pod
#       default:        default limits and requests
#         limit:
#           cpu:          role.lrange.min.cpu * role.lrange.ratio.cpu
#           memory:       role.lrange.min.memory * role.lrange.ratio.memory
#         request:
#           cpu:          defaults to whatever role.lrange.min.cpu is
#           memory:       defaults to whatever role.lrange.min.memory is
#       max:            maximum limits
#         cpu:            maximum cpu limit (4000m, 4 cpus)
#         memory:         maximum memory limit (4096Mi, 4Gi)
#       min:            minimum requests
#         cpu:            minimum requested cpu (50m, 5%)
#         memory:         minimum requested memory (64Mi)
#       ratio:          max limit-to-request ratio (x-to-1)
#         cpu:            cpu lrr (4)
#         memory:         memory lrr (4)
#
# IMPORTANT: XXX: ALL COMPUTE UNITS MUST BE IN milicores AND Mi!
