Support MCP tools caching

[NicoleMGomes]

Describe the Problem

When listing tools, cache should be enabled and evicted when case consumer want.

Note: It should use similar approach for what is already in place for token caching

Propose a Solution

# caches MCP tools for 600 ms and resets in case callback_to_evict is called
options = { ttl="600", envict=callback_to_evict }
agw_client.list_tools(cache=options)
