Inconsistent meta-variable naming in the parser

[jstolarek]

Variables in the parser use inconsistent naming scheme. For example, for the reserve-deposit command:

--deposit-reserve-asset ASSET-SCRIPT-HASH
--reserve-asset-name RESERVE_ASSET_NAME

Notice how one variable uses dashes to delimit words, whereas other uses underscores. The dashes seem to be an oversight from the work on native token reserve management. The default we have always used are underscores and we should fix the parser to consistently use underscores in the metavariables.
