goal: user defined scheme to connect to remote host

[win-t]

Related to #2904

I use this patch to connect to a remote node

for example, connecting to https://algonode.io/api/

$ echo https://mainnet-api.algonode.cloud > algod.net
$ echo 0000000000000000000000000000000000000000000000000000000000000000 > algod.token
$ goal -d $PWD account info -a ZW3ISEHZUHPO7OZGMKLKIIMKVICOUDRCERI454I3DB2BH52HGLSO67W754
