Fix URL override not being used for API calls

[agrare]

The openapi generated ApiClient/Configuration classes have a way to to pass scheme, host, and base_path but they are ignored and Configuration#server_settings is used unless server_index is set to nil

There appear to be two ways to do this in an OpenAPI generated gem.

You can either provide scheme, host, and base_path with server_index=nil (https://github.com/xlab-si/intersight-sdk-ruby/blob/main/lib/intersight_client/configuration.rb#L193-L194)
Or you can provide server_variables that override the variable parameters in the servers section of the openapi spec (https://github.com/xlab-si/intersight-sdk-ruby/blob/main/lib/intersight_client/configuration.rb#L196-L213)

The latter seems like the "nicer" way to do it, only downside seems to be that the scheme can't be overridden.

We had some existing specs which tested a "http://intersight.localdomain:8080" case so I went with the server_index=nil route

String comparison of the URL has me slightly concerned, only because someone could also put "https://intersight.com/" (trailing slash), and that should technically go through here too - I wonder if there's way to parse the URL object anyway, then check if url.hostname == "intersight.com"?

[agrare]

Yeah a bunch of edge cases here, if someone sets url=http://intersight.com:1234/some-other-base-path I'm not sure that we would want to default to https://intersight.com which is what would happen there.
Can certainly check each component of the URI though the code is going to get a little gross though :D

[agrare]

Maybe URI::Generic#== can rescue us here

>> URI.parse('https://intersight.com') == URI.parse('https://intersight.com:443/') 
=> true
