[Jsonnet] Ingester ConfigMap changes

[annanay25]

These are the different configmaps we run at the moment

tempo                    2      76d
tempo-compactor          2      76d
tempo-querier            1      76d
tempo-query              1      76d
tempo-query-frontend     1      76d

There are two issues to fix:

• The ingester (and distributor) should get its own configmap which allows modification of ingester specific values without rolling out other components (in this case - the distributor, which shares the tempo configmap with the ingester)
• The ingester statefulset should get a new annotation with the config hash of the ingester configmap so that it is auto-rolled when the config changes.
