KV Value Update handles Data wrongly

Describe the bug

When trying to set a value in the KV Store metadata needs to be provided, but gets merged into the value and no meta data gets set.

In [29]: response = client.kv.namespaces.values.update(key_name="test", value="MY VALUE", metadata="{}", **kv.params)

In [30]: print(client.kv.namespaces.values.get(key_name="test",  **kv.params).text())
{"metadata":"{}","value":"MY VALUE"}

In [31]: print(client.kv.namespaces.metadata.get(key_name="test",  **kv.params) is None)
True

The problem seems to be caused from the whole body of the request being used as the actual value. The behaviour seems to be correct when manually specifying the request's content tye as multipart/form-data:

In [38]: response = client.kv.namespaces.values.update(key_name="test", value="MY VALUE", metadata="{}", **kv.params, extra_headers={"Content-Type": "multipart/form-data"})

In [39]: print(client.kv.namespaces.values.get(key_name="test",  **kv.params).text())
MY VALUE

In [40]: print(client.kv.namespaces.metadata.get(key_name="test",  **kv.params))
{}

This should probably be the default behaviour as it shouldn't be necessary to explicitly override the content type. On the other hand metadata should not be required in which case the whole body could be set as value

To Reproduce

1. Call values.update() with a value and metadata. Both are set as the actual value.
2. metadata.get() doesn't return any metadata.
3. Metadata is returned with the value upon calling values.get().
