Clarify HPCS instance type for KMIP

[sandeep-at-ibm]

Please clarify in "Before you begin" section to provision a Standard Instance of HPCS.

Customer provisioned a UKO instance as that is the first option on the provisioning panel on IBM Cloud and tried to go through the KMIP provisioning process and went through multiple trouble shooting discussions, before it came to me.

For KMIP / VMware services, a Standard Instance is required.

Thanks @TiffanyLiIBM It'll be great if you can highlight the "Standard Plan" part of the bullet

@sandeep-at-ibm We are not allowed to add highlighting just for emphasis in docs. However, I have made some more changes to the title and the overall flow. Hope it makes "standard plan" stand out.
