METRON-1289: Alert fields are lost when a MetaAlert is created
## Contributor Comments
This PR fixes a bug in the ElasticsearchMetaAlertDao that incorrectly
updates the included alerts. To reproduce this error, pick any alert and
record it's guid. Then create a metaalert with the
http://node1:8082/swagger-ui.html#!/meta-alert-controller/createUsingPOST
endpoint:
```
{
"groups": [
"string"
],
"guidToIndices":
{"dcb3afed-1b68-d88a-7adb-f38183867920":"bro_index_2017.11.01.13"}
}
```
Now perform a lookup on the same alert with the
http://node1:8082/swagger-ui.html#!/search-controller/getLatestUsingPOST
endpoint:
```
{
"guid": "dcb3afed-1b68-d88a-7adb-f38183867920",
"sensorType": "bro"
}
```
The result only contains the "metaalert" field:
```
{
"metaalerts": [
"87ce1d82-aa09-4a1a-8be9-b9e7b76859b9"
]
}
```
This PR corrects this error by updating the alert with the full object
instead of a partial object. After this PR, following the steps above should
return the full object including the new "metaalert" field.
A `getAllLatest` function was added to make IndexDao match the pattern used
for findOne. An HBase implementation was not added because it seemed
unnecessary but it could be if it makes sense. Test cases were added to catch
the error above and for the new `getAllLatest` function. This has been
verified in full dev.
