Merged PR 3625: Excludes new dash users without id deal

# Description

This PR has 2 commits:
- The first one handles the removal from the computation any user that has not an id deal properly set. I just created a boolean field in int_core__user_host that identifies if the host has no id_deal. Then apply the new condition in the 2 main usages of New Dash info.
- The second one cleans New Dash KPIs. Since we do not have anymore users without deals, it means that the identification of the host/account is going to be exactly the same if done by id_user_host or id_deal. I hated having id_user_host in KPIs so I've removed it :)

Lastly, this should speed up massively the execution. Not because there's improvements on the code but rather the reduction of data.
