refactor: Add ConnectionFactory to EdOperation && remove PooledConnectionFactory…

Hey Daniel,

What do you think about this change? It's simple and allows for EdServiceTemplate to be more extensible.

What's new?

• EdOperation includes ConnectionFactory
  • DirectoryType and DirectoryEnv may not necessarily indicate where connections are coming from
• EdServiceTemplate can be extended using non-pooling connection factories.

merged

So I went ahead and merged these changes in, nothing too major, let me know what you think. I will go ahead and include the fact that to use EdAuth your IP must be whitelisted at https://code.vt.edu/rtilley/edauth-exceptions
