MAST query times out after 600s

The default config file does not seem to have an entry for [mast] and conf.timeout is set by mast/__init__.py to a hard coded 600s.
This value is way to small to do any JWST related MAST queries. As this is not well documented, I wanted to report this here.

Read mast/__init__.py and inspect the default config file, focusing on how conf.timeout is initialized and whether a [mast] entry is supported. Verify the current behavior for a JWST-related MAST query; done should make the timeout configurable or appropriately documented so users are not limited by the hard-coded 600s value.
