handle BSS APIs not available in all regions

[swaroopar]

Currently the BSS APIs are not available in all regions. For example on eu-west-101 region, there is no API available. So if the the user is using his eu-west-101 credentials, then call to bss and bss-intl will fail since the eu-west-101 IAM is different to other regions. New proposed solution to be tried is

• [ ] Try bss-intl -> if fails, try bss
• [ ] if even that fails, then try the public API which is also used by the page - https://www.huaweicloud.com/intl/en-us/pricing/calculator.html#/ecs this uses the API and does not need any credentials. -> https://portal-intl.huaweicloud.com/api/cbc/global/rest/BSS/billing/ratingservice/v2/inquiry/resource
• [ ] Remove the extra check for text "CBC". https://github.com/eclipse-xpanse/xpanse/blob/main/plugins/huaweicloud/src/main/java/org/eclipse/xpanse/plugins/huaweicloud/price/HuaweiCloudPriceCalculator.java#L110
• [ ] Currently when we get errors, we ignore it and directly set only the license price and markup price as recurring price. This must be avoided - https://github.com/eclipse-xpanse/xpanse/blob/main/plugins/huaweicloud/src/main/java/org/eclipse/xpanse/plugins/huaweicloud/price/HuaweiCloudPriceCalculator.java#L110 sample request
