[EXP] Increase default remote timeout - #6001

@pllim - This looks good to me given the assumption this will help the tests pass. If they become unstable again, we can revert the default again.

I don't think this need a changelog, and milestone doesn't matter much as the bugfix branch will only have a few CI runs before release.

Well... Look at that... Remote tests failing even here! Maybe this is not the correct solution after all. 🤔

@pllim - let's hope it was a fluke, only one of the remote ones were failing (now restrted) while previously it was all of them.

That test passed now. Remaining failures unrelated.

There are a few timeouts again, so I'm merging this in the hope it will have have some positive effect for those.

FWIW https://travis-ci.org/astropy/astropy/builds/229908432 is all green except the ufunc thingy.

Lovely, I'll add divmod shortly.

Ops, and also this but we'll see if it is consistent or transient.

@mhvk , did you post the wrong link? It shows green with

8985 passed, 121 skipped, 80 xfailed, 3 xpassed, 1 pytest-warnings in 394.27 seconds 

Ah, I hadn't realised that if one restarts a test, the old log gets overwritten...
