T5702: SNMP add interface-mib max-interfaces-number and prefix

- Allow to configure only required interface prefixes

  set service snmp mib interface 'eth'
  set service snmp mib interface 'bond'

 include_ifmib_iface_prefix eth bond

Sets the interface name prefixes to include in the IF-MIB data collection.
For servers with a large number of interfaces (ppp, dummy, bridge, etc)
the IF-MIB processing will take a large chunk of CPU for ioctl calls.
A set of space separated interface name prefixes will reduce the CPU
load for IF-MIB processing. For example, configuring
"include_ifmib_iface_prefix eth dummy lo" will include only interfaces
with these prefixes and ignore all others for IF-MIB processing.

- Allow to configure maximum interface number

  set service snmp mib interface-max '100'

  ifmib_max_num_ifaces NUM

Sets the maximum number of interfaces included in IF-MIB data collection.
For servers with a large number of interfaces (ppp, dummy, bridge, etc)
the IF-MIB processing will take a large chunk of CPU for ioctl calls
(on Linux). Setting a reasonable maximum for the CPU used will
reduce the CPU load for IF-MIB processing.  For example, configuring
"ifmib_max_num_ifaces 500" will include only the first 500 interfaces
based on ifindex and ignore all others for IF-MIB processing.
