Prune app history states by keeping the recent heights and deleting old heights

Synopsis ​

Prune app history states by keeping the recent heights and deleting old heights. The pruning option is provided via the '--pruning' flag or alternatively with '--pruning-keep-recent'

	For '--pruning' the options are as follows:
	
	default: the last 362880 states are kept
	nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node)
	everything: 2 latest states will be kept
	custom: allow pruning options to be manually specified through 'pruning-keep-recent'.
	besides pruning options, database home directory and database backend type should also be specified via flags
	'--home' and '--app-db-backend'.
	valid app-db-backend type includes 'goleveldb', 'cleveldb', 'rocksdb', 'boltdb', and 'badgerdb'.
