Colmena

The major new feature in this release is a new TaskServer implementation based on FuncX. This allows for easier configuration of multi-site applications.

What's Changed
* Add a FuncXTaskServer by WardLT in https://github.com/exalearn/colmena/pull/40
* Fix a race condition in event_responder by WardLT in https://github.com/exalearn/colmena/pull/42


**Full Changelog**: https://github.com/exalearn/colmena/compare/v0.1.3...v0.2.0

A few minor changes
- Provide options to look up parameters for some agents at runtime from class attributes.
- Properly use timeout when waiting for Semaphore objects

Simplifies implementing a common pattern of thinking applications by adding logic that automatically re-allocates resources when a function is launched by an event trigger.

Renamed the components to match our new nomenclature. For this release, "method server" has been renamed to "task server"
