[Request] Add 'service' to the Entity Store

[machadoum]

Description

We're introducing the entity type 'service' to the Entity Store. Previously, only 'user' and 'host' were supported.
The new 'service' entity type should be displayed on all pages where the 'user' and 'host' entities are displayed. Ex: Entity Store page, Risk Score page, Entity Dashboards.
It will allow users to investigate and protect the services installed in their environment easily.
The user only needs to enable the entity store to install the' service' entity type.

Hi @machadoum @jaredburgettelastic, just want to confirm that entity store and service entity type are still planned to be released in serverless in early Feb? Adding an estimated date/week for serverless release to tickets would be really helpful, even if it ends up changing later on. 🙏
Also, is there a test environment you could share for this feature? https://kibana.siem.estc.dev/ was EOLed at the end of last year.

@natasha-moore-elastic Done! Updated the ticket above.

Yes, early February is still our target.
