start-storybook: Allow passing node flags

[cookch10]

Is your feature request related to a problem? Please describe.
When using react storybook with the knobs addon, some stories which have a large / complex props / json structure can cause the URL length to go beyond the maximum value defined by node, which causes the local dev server to respond with an error. The solution I have found is to pass the --max-http-header-size flag to node with an appropriate value, which mitigates this issue. Unfortunately it doesn't seem like calling start-storybook allows passing any parameters other than those for storybook.

For example, changing start-storybook.cmd to look like the following solves the issue:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max-http-header-size 90000  "%~dp0\..\@storybook\react\bin\index.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max-http-header-size 90000  "%~dp0\..\@storybook\react\bin\index.js" %*
)

Describe the solution you'd like
Would it be possible to update start-storybook to allow passing non-storybook parameters / flags?

Describe alternatives you've considered
I am welcome to any alternative approaches which could solve the issue.

Additional context:
I'm on Windows 7 x64 OS with Node v10.16.0 and npm v6.10.1

@cookch10 What version of storybook are you using?

[cookch10]

@shilman , @storybook/react version 3.4.12.

[shilman]

@cookch10 if you upgrade to v5 we've shortened the URL structure, which might be a workaround. i think yours is a reasonable feature request tho.

Thanks @shilman , that's helpful, but doesn't solve the issue for me in all cases. Looking forward to this future enhancement!

I recommend importing @storybook/core-server directly and calling it's APIs if you find that somehow the CLI isn's giving you enough flexibility.
