Forwarder version in dmc_forwarder_assets lookup is updated in un unreliable way

Hi 

Lookup table doesn't contain the current version of the forwarder. Instead, the highest ever seen version is stored. 

For example, if forwarders were downgraded, it's necessary rebuild the forwarder assets table manually.

Issues are caused by line 4 "max(version) as version" in search "DMC Forwarder - Build Asset Table"

`dmc_set_index_internal` sourcetype=splunkd group=tcpin_connections (connectionType=cooked OR connectionType=cookedSSL) fwdType=* guid=*
