Define a typealias for HttpHeaders and use it where ever needed.
Inturn map this to email.message.Message and dict for now.
If and when python evolves Http Headers type into better one,
need to replace in only one place.
Add a ToolManager class which
* maintains the list of tool calls and inturn allows any given
tool call to be executed and response returned along with needed
meta data
* generate the overall tool calls meta data
* add ToolCallResponseEx which maintains full TCOutResponse for
use by tc_handle callers
Avoid duplicating handling of some of the basic needed http header
entries.
Move checking for any dependencies before enabling a tool call into
respective tc??? module.
* for now this also demotes the logic from the previous fine grained
per tool call based dependency check to a more global dep check at
the respective module level
