SDK: framework.TypeKVPairs only handles one KV pair.

[iloving]

Describe the bug
The type name and all the related documentation say that this is supposed to create a map from one or more KV pairs. It does not. It finds the first =, then everything on the left is the key and everything on the right is the value. I have have tried formatting the string in a variety of ways, to no avail.

To Reproduce
Steps to reproduce the behavior:

1. Implement code that uses frakework.TypeKVPairs
2. Try to pass a string with multiple k/v entries

Expected behavior
If I pass the string "A=a,B=b,C=c", then I should get a map of { "A":"a";"B":"b"; "C":"c" }.

Environment:

• Vault Server Version (retrieve with vault status): 1.20
• Vault CLI Version (retrieve with vault version): 1.20
• Server Operating System/Architecture: Linux/amd64

Vault server configuration file(s):

# Paste your Vault config here.
# Be sure to scrub any sensitive values
