Test service abstraction code loading

The abstraction modules e.g. `Fog::Compute` have a list of registered
providers. All of these providers should be loaded correctly when
accessed with `Fog::Service[:provider]`

These tests hit each endpoint expecting `ArgumentError` from each
provider caused by the lack of credentials.

Credentials are stubbed out to not cause false results when the test
environment does have credentials for a service.

Some services do not have requirements so do not raise the expected
error. These special cases are just asserted. If they are not loaded the
specs fail again.
This limits 1.8.7 to use `activesupport-v3.2.21`

Versions greater than 4.0 dropped 1.8.7 support but it appears the
Travis build environment just updated so this appeared.

[Fog 2.0] Remove 1.8.7 support

This is the official commit to drop Ruby 1.8.7 support from fog.

This is a backwards incompatible change (for hopefully obvious reasons)
so will be part of the next MAJOR fog release `v2.0`

Ruby 1.8.7 is no longer supported by the language developers.

Anyone needing to stay on Ruby 1.8.7 such as users of LTS distros should
remain on the `v1.x` series of fog.
