Steps to reproduce:

1. start use walk[] based template against SNMP device
2. receive 'only partial data received, cannot retrieve OID:'
3. check trace logs of the snmp poller - only some OID returned nothing, result - all dependent items has no recent data

Expected:

• Configurable retries count, suggestion is to reuse 'Max repetition count' knob and rename it to 'Max repetition/retries' count, also there is a related ZBXNEXT-10111 (for mobile networks better to reduce retries)
• Modify LLD part logic, so the partial/inconsistent received data will be skipped for LLD and even partial data will populate values for dependent items.
