lookup('service_memory_mb', application_id, service_name, share) returns
a share of a service's mem_limit in whole MiB. It resolves the limit the
way sys-svc-container resolves the container's own: the named service,
then the role's primary entity, then RESOURCE_MEM_LIMIT.
It replaces the three filters of memory_filters, each with its own unit
parser and its own idea of the limit: Redis maxmemory at 0.8 of the
limit, and the Confluence and Jira heap at 0.7 and 0.35.
The central Redis (409 MiB), Confluence (5734/2867) and Jira (4300/2150)
keep their values. A Redis sidecar without a mem_limit of its own does
not: the filter fell back to a fixed 256m, which gave 204 MiB, while the
lookup takes the limit that container really runs with, the primary
entity's. That moves 25 roles to between 409 and 3276 MiB.
The heap clamps of the old filters are gone: the 1024 MiB floor, limit
minus 1024, the 12288 cap and Xms bounded by mem_reservation.
