sonic-db-cli should support EVAL operation, one app script use it in this way

test :
admin@ASW-7005:~$ sudo /tmp/sonic-db-cli APPL_DB EVAL "return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}" 2 k1 k2 v1 v2
['k1', 'k2', 'v1', 'v2']

@qiluo-msft we need this merged first and then we can move further on the replacement of redis-cli

[qiluo-msft]

Can you unify both branches? execute_command is quite general for both cases. #Closed

print "Example 3: sonic-db-cli APPL_DB HGET VLAN_TABLE:Vlan10 mtu"

Could you add one more example? And use python heredoc https://en.wikipedia.org/wiki/Here_document#Python ? #Closed
