Show list of discovery rules having errors for a selected host group

Summary

Currently it is possible to see discovery rules linked to a single host without any filtering options. It is impossible to see all discovery rules of a host group or see discovery rules having errors. It has to be improved.

Acceptance

List of discovery rules must support filtering by various attributes similarly to already existing filter used for items:

1. Hosts groups
2. Hosts
3. Name
4. Key
5. Type
6. Type of information
7. Keep lost resources interval
8. SNMP OID
9. State
10. Status

Use cases

1. I want to see list of discovery rules having errors for a selected host group
