Update Coordinated Throughput Controller to 0.1.1

[ammyrohilla5050-dot]

Updates Coordinated Throughput Controller to version 0.1.1.

Changes:

• Adds the 0.1.1 release jar to Plugin Manager metadata.
• Updates the plugin description to position it as a replacement for JMeter's standard Throughput Controller when sibling flows must be mutually exclusive.
• Notes that it fixes cases where multiple sibling Throughput Controllers can run in the same iteration and overwrite variables or execute conflicting business paths.

Release:
