Unused code in integration tests

[Mzack9999]

Nuclei version:

main|dev

Current Behavior:

A lot of integration tests cases declares a lot of routerErr variables that are not used in handlers and should be removed if not necessary. For example:

• nuclei/v2/cmd/integration-test/dns.go

  Line 35 in 16d15e2

  var routerErr error

  (DNS)

• nuclei/v2/cmd/integration-test/http.go

  Line 490 in 16d15e2

  var routerErr error

  (HTTP)

• nuclei/v2/cmd/integration-test/network.go

  Line 102 in 16d15e2

  var routerErr error

  (Network)

• nuclei/v2/cmd/integration-test/template-dir.go

  Line 22 in 16d15e2

  defer os.RemoveAll(getTemplatesDir())

  
  And so on

Expected Behavior:

Removed unused code
