Reload cell code without restarting server

[dannongruver]

Problem

Currently when executing a cell via kernel_gateway.notebook_http mode, the cell's code/logic stays the same even when changing the cell after starting the kernel_gateway.

For example, if kernel_gateway starts and the cell's content is...

# GET /hello/world
print(f"hello")

...then calling http://127.0.0.1/hello/world gives hello response. If that cell changes to...

# GET /hello/world
print(f"new change")

...and the kernel_gateway isn't restarted then http://127.0.0.1/hello/world responds with hello still instead of new change

Proposed Solution

Monitor for file changes and reload the cell's code.

Is there a way to restart the server without killing the process?
