Deprecate common.Bind() and relatives

[codebien]

Problem statement

Now that k6 has a new and cleaner API for JS modules and most of the internal modules had been migrated we can consider deprecating the common.Bind() method for having a unique and consistent way of extending the k6's JS API.

Proposed change

v0.36.0

• Mention that we plan to deprecate them in the release notes

v0.37.0

• Submit and merge a PR for Migrate js/grpc to ModuleV2 #2343
• Add a deprecation comment and relative log warning for common.Bind()
• Add a deprecation comment for connected APIs

Below a list of the connected methods to deprecate:

$ rg '\bWith.*context.Context' -g '!vendor'
api/common/context.go
33:func WithEngine(ctx context.Context, engine *core.Engine) context.Context {

js/common/context.go
37:func WithRuntime(ctx context.Context, rt *goja.Runtime) context.Context {
51:func WithInitEnv(ctx context.Context, initEnv *InitEnvironment) context.Context {

lib/context.go
34:func WithState(ctx context.Context, state *State) context.Context {
48:func WithExecutionState(ctx context.Context, s *ExecutionState) context.Context {
62:func WithScenarioState(ctx context.Context, s *ScenarioState) context.Context {

From an internal discussion:

Removing WithExecutionState and WithScenarioState might not be needed or will need more methods on the modules.VU interface

v0.38.0 or v0.39.0

• Drop common.Bind and context-based utils #2385
