refactor(agent): Agent modular refactoring

[fangyinc]

Description

1. Refactor

Refactor the agent code into four core modules according to the paper A survey on large language model based autonomous agents

2. More flexible Profile module

A more flexible Profile module implementation that supports creating agent profiles from environment variables, databases, and other implementations.
Note: In order to be more clear and intuitive, use jinja2 to render the prompt template of agent profile.

3. Unified memory framework support

Supports sensory memory, short-term memory, long-term memory and hybrid memory.

How Has This Been Tested?

Run all python codes in the examples/agents directory.
