fix(shared): retry dynamodb queries more times BM-1008 (#3254)

#### Motivation

Dynamo is sometimes erroring with throttling exception, we currently
have retries set at 3 retires

```
stack: ThrottlingException: Throughput exceeds the current capacity of your table or index. 
DynamoDB is automatically scaling your table or index so please try again shortly.
If exceptions persist, check if you have a hot key: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-design.html
    at qke (/var/task/index.js:20:5520)
````

#### Modification

Increase the retry count to 5, so that it retries more before erroring.


#### Checklist

_If not applicable, provide explanation of why._
