[7.0.x] Fix sortorder dep

[bernardjkim]

Description

The vbom.ml domain was taken down and this broke the vbom.ml/util/sortorder dependency: fvbommel/util#6. This PR adds a temporary workaround by replacing the import paths from vbom.ml/util/sortorder -> github.com/fvbommel/sortorder.

Usage

• make fix-sortorder should be run after updating dependencies. This will update the import paths.
• make dep-ensure combines dep ensure and fix-sortorder target.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Internal change (not necessarily a bug fix or a new feature)

Linked tickets and other PRs

• Refs can't resolve vbom.ml/util dependency fvbommel/util#6

Additional information

When attempting to update dependencies using dep, the update fails with the follow issue:

$ dep ensure
Solving failure: unable to deduce repository and source type for "vbom.ml/util": unable to read metadata: unable to fetch raw metadata: failed HTTP request to URL "http://vbom.ml/util?go-get=1": Get http://vbom.ml/util?go-get=1: dial tcp: lookup vbom.ml on 127.0.0.53:53: no such host

How should this target be used when updating dependencies?

How does it affect version/7.0.x? All I saw were issues with go mod which is not used in 7.x.
As a side note, would it be possible to workaround this with making vbom.ml/util/sortorder an explicit dependency (i.e. list in Gopkg.toml) and create an alias to the new location?

I've tried making vbom.ml/util/sortorder an explicit dependency and specifying a source, but it didn't seem to fix the issue. Not sure if I implemented it correctly or if there is a different way to create an alias, but this is what I tried.

[[override]]
  name = "vbom.ml/util/sortorder"
  source = "github.com/fvbommel/sortorder"
  version = "v1.0.1"

$ dep ensure
The following issues were found in Gopkg.toml:

  ✗ unable to deduce repository and source type for "vbom.ml/util/sortorder": unable to read metadata: unable to fetch raw metadata: failed HTTP request to URL "http://vbom.ml/util/sortorder?go-get=1": Get http://vbom.ml/util/sortorder?go-get=1: dial tcp: lookup vbom.ml on 127.0.0.53:53: no such host

Ok, it looks like it's an old issue with dep.
Maybe we can wrap it as a make target - something like make dep-ensure - so it does the replacement automatically?

@r0mant, @a-palchikov
Added some additional information on issue with 7.0.x, and added a usage section in the original comment for information on make target usages. Use target make dep-ensure will update the dependencies and also fix sortorder import paths.
