Order CLI flags

[fdymylja]

At the moment flags of commands are merged together with cosmos-sdks default ones, so when the helper command is printed flags are put all together in an alphabetical ordered way.

Example:
Flags:

-a, --account-number uint      The account number of the signing account (offline mode only)
    --account-renew int        account duration in seconds before expiration (default 10000000)
-b, --broadcast-mode string    Transaction broadcasting mode (sync|async|block) (default "sync")
    --domain string            name of the domain you want to register
    --dry-run                  ignore the --gas flag and perform a simulation of a transaction, but don't broadcast it
    --fees string              Fees to pay along with transaction; eg: 10uatom
    --from string              Name or address of private key with which to sign

Try to order it in a way that the first ones are msg related flags and the other ones are the one inherited from the cosmos sdk.
