Fix for Issues984 985

[allmightyspiff]

• By default, the gpu0 price id is added to the list first, this fixes the issue SLCLI - The item GPU1 is set instead of GPU0 when ordering baremetals #984.
• The gpu0 and gpu1 are added to the list if the GPU KeyName is added twice in the order. Fix for SLCLI - Baremetal servers cannot be ordered with two gpu items #985
• If customer requires 2 GPU items they must to add the keyName twice, an expected API exception is raised when the GPU keyNames are different.

Try with following command:

slcli order place --verify --billing monthly --complex-type SoftLayer_Container_Product_Order_Hardware_Server DUAL_E52600_V4_12_DRIVES DALLAS12 REBOOT_KVM_OVER_IP UNLIMITED_SSL_VPN_USERS_1_PPTP_VPN_USER_PER_ACCOUNT NESSUS_VULNERABILITY_ASSESSMENT_REPORTING NOTIFICATION_EMAIL_AND_TICKET 1_IP_ADDRESS AUTOMATED_NOTIFICATION MONITORING_HOST_PING BANDWIDTH_500_GB REDUNDANT_POWER_SUPPLY INTEL_TXT_TRUSTED_EXECUTION_TECHNOLOGY OS_UBUNTU_16_04_LTS_XENIAL_XERUS_MINIMAL_64_BIT INTEL_INTEL_XEON_E52620_V4_2_10 RAM_128_GB_DDR4_2133_ECC_REG 10_GBPS_REDUNDANT_PUBLIC_PRIVATE_NETWORK_UPLINKS DISK_CONTROLLER_NONRAID HARD_DRIVE_1_9TB_SSD_SED_5DWPD HARD_DRIVE_2_00_TB_SATA_2 HARD_DRIVE_3_8TB_SSD_SED_3DWPD GPU_NVIDIA_TESLA_K80 GPU_NVIDIA_TESLA_K80
