Exclude some lines from the line-length-limit rule using regular expressions

[james-johnston-thumbtack]

Is your feature request related to a problem? Please describe.
Sometimes a line is unavoidably long and the line-length-limit rule triggers on it anyway, and a comment-based exclusion must be defined. For example:

// revive:disable:line-length-limit To allow go generate command
//go:generate go run ../../../cmd/stackwrapper/main.go -output stack_wrapper.go -type Monetization -dir ../../thrift/monetization/service -output-type StackWrapper

//revive:enable

In this case, the go:generate command must remain on one line, and there is no way to wrap it to a second line. One proposal to do so was declined: golang/go#46050

Other examples may also exist: for example users may want to carve out exclusions for long URLs (i.e. lines that match https://).

While it is possible to carve out exclusions every time this happens such as in the code example above, it is cumbersome to do so.

Describe the solution you'd like
A similar standalone linter, the lll linter, offers an exclude parameter which excludes lines matching a regular expression. If the line-length-limit rule could offer a similar option to exclude lines based on a regular expression, then we could set it to exclude checking lines with a pattern like go:generate.

Describe alternatives you've considered
Issue #701 proposes a somewhat similar scheme of excluding rules based on whether the filename matches a regular expression. Rather than have a line exclusion specific to line-length-limit, we could allow excluding any rule based on whether the line matches a regular expression. This could be more generic if other rules could benefit from line-regexp-specific exclusions.

Upon further research, I found a way to do this using golangci-lint when revive is used by that lint aggregator:

issues:
  exclude-rules:
    - linters:
        - revive
      text: "line-length-limit"
      source: '^\s*//go:generate |https?://'

This will exclude all lines matching the regexp that were flagged by the line-length-limit rule.

Obviously, this won't help anyone who isn't using golangci-lint.
