Add HumanTool class for agent-human interaction

[NJordan72]

This pull request introduces a new HumanTool class that extends the base Tool class. The purpose of this class is to allow agents to seek guidance from a human when they are stuck or unsure of what to do next.

Key changes include:

• A new HumanTool class has been added to represent the tool for agent-human interaction.

This enhancement will enable the agent to better handle situations where its knowledge or capabilities are insufficient by allowing it to seek assistance from a human.

Hey I don't quite understand this one - it just echoes back what the agent calls the tool with?

@jacoblee93 It was ported from the python version

Seems like there's some other components in the Python version to make it functional: https://github.com/hwchase17/langchain/blob/master/langchain/tools/human/tool.py

Could you add them and add an integration test?
