Fix warnings and errors for ruby 2.7

[Nautigsam]

Ruby 2.7 causes many depreciation warnings. I tried to remove the majority of them.

I still get some tests failing in test/unit/plugins/providers/docker/driver_compose_test.rb. One example of a test failing:

$ bundle exec rspec test/unit/plugins/providers/docker/driver_compose_test.rb -e "sets container name"
Run options:
  include {:full_description=>/sets\ container\ name/}
  exclude {:windows=>true}

VagrantPlugins::DockerProvider::Driver::Compose
  #create
    sets container name (FAILED - 1)

Failures:

  1) VagrantPlugins::DockerProvider::Driver::Compose#create sets container name
     Failure/Error: before { expect(subject).to receive(:execute).with(*compose_execute_up) }

I do not know how to fix this. Does someone who is more fluent in Ruby could help?

Hi there,

Thank you for this PR. Unfortunately, just swapping out CGI for URI does not always result in the same values being generated. This can result in a change in the path to a locally installed box causing Vagrant to "lose" it and not be able to detect it. #11814 includes an update for this to continue using the existing escaping implementation, just via a non-obsolete method.

Cheers!
