Minor changes to gnmi plugins

Remove the replace of "-" by "_" : makes too much confusion
Change native tag "source" to "device"

Add Xreducer plugin

Need for latest OpenJTS version for simplify Profile creation. New plugin:

// Tag and field xreducer
// It all to keep only the most significant elem of an XPATH
// /elem1/elem2/elem3 will be processed and only elem3 will be kept
// we support per tag or field reducing
// keyword "all" as key will reduce all

[[processors.xreducer]]
[[processors.xreducer.tags]]
//field to reduce - "All" will change all tags
key = "value"
[[processors.xreducer.fields]]
// field to reduce - "All" will change all fields
key = "value"

Add long_field flag in gnmi plugin

This new option will allow to keep full path for field name. This is in prevision of the new Profile Maker tool in OpenJTS

New bytes2float gnmi option

Add a new option for gnmi plugin: "bytes2float"

This option is a boolean (default = false) which indicates to gnmi plugin to convert on the fly 4 bytes array to float. This is for supporting oc:ieeefloat32 which is a typedef to a byte_val with a length of 4
