Kemp / Progress LoadMaster MIBs

Source bundle: LoadMaster 7.2.63.3.23e1735.RELEASE

The directory is named after the one4net enterprise OID (1.3.6.1.4.1.12196)
defined in ONE4NET-MIB, following the repository's vendor naming convention.

Local fixes:
  - B100-MIB and IPVS-MIB: import Gauge32 from SNMPv2-SMI, as it is used
    by their connection counters but missing from the vendor imports.
  - Remove trailing whitespace from the vendor files.
