Creating jsession id

[gargnipungarg]

Enhancement Description

With current endpoint in HTTP streamable protocol -

• We hit /mcp endpoint, which creates session id and performs a temporary redirect to /mcp/ for actual POST API endpoint. This does not seem very production grade setup

• If we hit directly /mcp/, then there is no way to find session id

Use Case

Hosting session id creation via API for production application hosting

Proposed Implementation

We can abstract session id creation as an API payload

For example - 

For listing tools we have - "method":"tools/list"
For calling tool, we have - "method":"tools/call"

Similarly we can create "method":"create session"
which returns session id
