Overriding with context manager (one and multiple providers)

[nightblure]

I implement two little features for ease of use during tests:

1. overriding one provider with a context manager. Now you can use it like this:

# old waysome_provider.override(mock)
some_provider.reset_override()
# new waywithsome_provider.override_context(mock):
...

2. overriding multiple providers with a context manager. Now you can use it like this:

mock_1= ...
mock2= ...
# old waycontainer.provider_1.override(mock_1)
container.provider_2.override(mock_2)
# do somethingcontainer.reset_override()
# new wayproviders_for_overriding= {
"provider_1": mock_1,
"provider_2": mock2,
# more providers...
}
withcontainer.override_providers(providers_for_overriding):
# do something

@nightblure looks great, thanks!

we lose coverage on this line after I removed omit. is it acceptable to add # pragma: no cover here?

hmm, there is still a question about updating the documentation. I can try to add the relevant sections myself if you allow, or you will do this

[lesnik512]

@nightblure would be great if you'll add docs as well, but it's up to you. Anyway, thank you for your contribution!
