The advanced example:
curl -X POST <M3_COORDINATOR_IP_ADDRESS>:<CONFIGURED_PORT(default 7201)>/api/v1/services/m3db/namespace -d '{
"name": "default_unaggregated",
"options": {
"bootstrapEnabled": true,
"flushEnabled": true,
"writesToCommitLog": true,
"cleanupEnabled": true,
"snapshotEnabled": true,
"repairEnabled": false,
"retentionOptions": {
"retentionPeriodDuration": "2d",
"blockSizeDuration": "2h",
"bufferFutureDuration": "10m",
"bufferPastDuration": "10m",
"blockDataExpiry": true,
"blockDataExpiryAfterNotAccessedPeriodDuration": "5m"
},
"indexOptions": {
"enabled": true,
"blockSizeDuration": "2h"
},
"aggregationOptions": {
"aggregations": [
{ "aggregated": false }
]
}
}
}'

Contains blockDataExpiryAfterNotAccessedPeriodDuration which no longer seems to be a valid option. The above curl fails.
Please update example
