EI to have an additional config parameter for ER query parameter

[SantoshNC68]

Description

Today EI is using default query parameters towards ER service, we have a limitation towards this when the default value is set for the limit (100 events). If there are more than 100 events it will not aggregate the information.

Motivation

This is seen as a limitation when Aggregating the information which have more than 100 events linked.

Exemplification

When there are 200 events linked today the EI aggregation is limiting the response today to only 100 events.

Benefits

With this change it could potentially provide the user the option to choose how many events he expects from the query, if he is unsure he can use -2 value for the limit, which will follow all the linked events(unlimited)

Possible Drawbacks

Nothing that we see of.
