Modified KV Example

This is an improved example of usage for hashicorp/plugin

Modifications include:

• injection of zerolog logger into plugin mechanism.
• removal of unnesessary net/rpc
• capturing native stderr logs from Plugins in Main process
• proper logger calls from Plugins into main Process using bidirectional communication

This example builds a simple key/value store CLI where the mechanism for storing and retrieving keys is pluggable.

To build this example:

$ make

To run this example:

$ make run_put
$ make run_get
