Feature: Bazel Support

[sgammon]

Hey there Fullstory,

I have no idea if this is useful for you guys, but I added Bazel support in a fork because we need it in our environment. It's a pretty conventional add with Gazelle, and should be maintainable along those lines as well. If there is any interest, I would be happy to contribute it back :)

Changes enclosed

• [x] Add support for Gazelle and run it
• [x] Add baseline dependencies like proto and rules_python
• [x] Add support for external Bazel repos
• [x] Generate deps.bzl
• [x] Apply patches for transitive modules that don't build
• [x] Update to Go 1.18
• [ ] Known issues
  • [ ] The tests don't yet run

To build/run with Bazel

There are two ways to build and run, the way things are set up with Gazelle. There is, the (1) build/run from source way (which you should use during development), and the (2) run from bindist way (which downstream Bazel codebases should use).

Provided for easy copy/paste:

git clone git@github.com:sgammon/grpcurl.git -b bazel && cd ./grpcurl

Method 1: Local build/run

bazel build //:grpcurl

bazel run //:grpcurl -- -help

Method 2: Downstream run

First, the user adds the bindist to their own WORKSPACE, with:

workspace(
  # ...
)

grpcurl_version = "b8e91f6f5b182300c1bf1d3c3f5bf2c221d826cf"  # (or a release, like `v1.8.6`)

http_archive(
    name = "com_github_fullstorydev_grpcurl",
    sha256 = "40819664a05748f6af6cdc814ea70ca09b2a4e3b9d5f5515d459c43cb1e3c55d",
    strip_prefix = "grpcurl-%s" % grpcurl_version,
    url = "https://github.com/sgammon/grpcurl/archive/%s/archive.tar.gz" % grpcurl_version,
)

load("@com_github_fullstorydev_grpcurl//:grpcurl_repositories.bzl", "grpcurl_bindist_repository")

grpcurl_bindist_repository(
    name = "grpcurl",
    version = "1.8.6",
)

Then, they can run it in their own Bazel project easily with:

bazel run @grpcurl//:grpcurl

Support for method 2 is enclosed for Linux and macOS, although Windows would be relatively easy to add. All architectures are included that grpcurl is released for.

Update: I've pushed the same support for grpcui at fullstorydev/grpcui#188

I should also say, I'm happy to contribute a CI job, or Renovate config, etc., to reduce any potential maintenance burden in merging this. Thanks for such an awesome tool!
