Now , there are two API to set WiFi Password:
1：int32_t wifi_config_set_wep_key(uint8_t port, wifi_wep_key_t *wep_keys)
2：int32_t wifi_config_set_wpa_psk_key(uint8_t port, uint8_t *passphrase, uint8_t passphrase_length)
if user don't know the AP router's AuthMode/EncryptType，but only know the password
user can invoke both of the two APIs to set the Key.
Nots: WEP Key length has 5,13, 10,26。
if the password user set is not WEP key length，user no need to set the password by WEP Key Set API.
