LDContext equality

[jgarber-cisco]

Is your feature request related to a problem? Please describe.
I would like to mock LDClient#variation and expect it to be called with a particular context, but equality isn't implemented:

LaunchDarkly::LDContext.with_key("foo") == LaunchDarkly::LDContext.with_key("foo")
=> false

So if I try something like expect(ld_client).to receive(:variation).with('foo', my_context, false), I get a spec failure if my_context isn't the same exact Ruby object.

Describe the solution you'd like
LDContext should implement equality so two LDContexts can be compared. Even better, make LDContext quack like a hash so I can compare it to a hash, retrieve attributes like a hash, etc.

Describe alternatives you've considered
I've had to mock an alternate implementation for variation that returns the context key so I can check that variation was called with the right context. I'm also expecting the call with the feature flag name to ensure that it wasn't a different flag that was checked, but I have to use anything as a stand-in for the context.

expect(ld_client).to receive(:variation).with('foo', anything, false) # LDContexts don't have == implemented properly

Thank you for filing this issue. Both of those seem pretty reasonable.

I have filed a ticket for this in our internal system: sc-214802 for reference. I will update you here when progress is made on this request.

Thank you again!

Context equality and [] access were both added in v8.1.0!
