Enhancement: make channel names shorter in the metrics command

[YamatoSecurity]

When running the metrics command, sometimes the channel name is too long and the table overlaps like this:

After converting the Channel name abbreviations according to the channel_abbreviations.txt file, I would like to make the remaining channel names shorter by abbreviating the following words:

Microsoft => MS
Windows => Win
Operational => Op
Diagnosis => Diag
Package => Pkg
Server => Svr
Client => Cli
Management => Mgmt
Security => Sec
Connection => Conn
Application => App

For example, in the screenshot above, Microsoft-Windows-Diagnosis-PLA/Operational would become MS-Win-Diag-PLA/Op.

@YamatoSecurity Thank you for sending issue.
Could you tell us what you envision for the following questions?

1. This name shorter is only in metrics command?
2. Is These abbrevation defined by external config file? or hardcode?

Good questions!

1. I was thinking just the metrics command at first, but it would reduce size of the CSV and JSON file so maybe implement it there too if it is not too difficult.
2. I was thinking hardcoding at first, but it will probably need periodic updates so would be better in an external config file under rules/config/channel_abbreviations_generic.txt
