Set tenant ID for intrusion detection

[asincu]

Description

Set tenant ID in intrusion detection when installing in a multi-tenant management cluster.

Zero-tenant : tenant ID is not needed.
Single tenant with internal elastic (0.5 half tenant) : tenant ID is not needed, as we need to assume we make queries as MCM does
Single tenant with external elastic: Needs tenant ID, but talk to Linseed from tigera-elasticsearch namespace and Manager from tigera-manager namespace
Multi-tenant: Needs tenant ID, tenant namespace and per tenant services for Linseed and Manager.
