Assert in hashfiles that executionContext is available

* Bypass top level domain even if no_proxy specified it with leading '.'

E.g. no_proxy='.github.com' will now bypass github.com.

* Bypass proxy on all hosts when no_proxy is * (wildcard)

* Undo '.' stripping

* Simplify unit tests

* Respect wildcard even if it's one of many no_proxy items
