REST methods should handle redirects

[jsmartt]

Scenario/Intent

The REST methods should handle redirects. One issue I've already run into is that for Synergy Enclsoures, trying to get the script (enc.script) gives a 301 error message saying it has moved to a LogicalEnclosure uri.

I think we could implements something pretty similar to this, where we only follow redirects up to 3 or 5 times.

Because we need the data to re-submit the request, we'll need to handle this in the rest_api method, not response_handler.

Environment Details

• OneView SDK Version: 3.1.0
• OneView Appliance Version: All
• OneView Client API Version: All

Steps to Reproduce

With a client using api_version 300 as @client, talking to a v300 DCS...

@client.api_version = 300
OneviewSDK.api_version = 300
OneviewSDK::API300.variant = 'Synergy'

e = @client.get_all(:Enclosures).first
e.script

Expected Result

It to be able to get the script (following any redirects needed to get there)

Actual Result

I get this error:

OneviewSDK::RequestError: 301
from /usr/local/rvm/gems/ruby-2.2.4/gems/oneview-sdk-3.1.0/lib/oneview-sdk/rest.rb:162:in `response_handler'

@tmiotto , @ricardogpsf , @aalexmonteiro , @fgbulsoni or @piantola , do any of you have any concerns with this, or shall I implement it?

[tmiotto]

@jsmartt I have one concern that is to avoid being eternally redirected, maybe we should have a limit for it, or timeout.

By the way, I'm okay with you implementing it.

[jsmartt]

@tmiotto , correct. We'd definitely have to set a limit

[ricardogpsf]

@jsmartt I'm okay too with the idea of implementation.
