FEAT: add kernel params to `get template` commands output

[Masber]

I think, kernel params are only useful to check a single machine or compare two of them in different clusters for troubleshooting.

Therefore it should be ok showing kernel params when manta detects user is only requesting a single BOS sessiontemplate.

Another benefit of this would be to save screen real estate since kernel params takes a lot of space and probably needs formatting by breaking it down into multiple rows?
