expose channels in generated code as constants about asyncapi-codegen

[lerenn]

Hello @antonyc ! Thanks for your interest in this project 😃

So if I understood correctly, if we have, for example, this AsyncAPI document:

channels:
  ping:
    publish:
      operationId: ping
      message:
        $ref : '#/components/messages/Ping'

  pong:
    subscribe:
      operationId: pong
      message:
        $ref: '#/components/messages/Pong'

You would like to have this kind of code generated:

const (
    // PingChannelPath is the channel path for 'ping' operation
    PingChannelPath = "ping"
    // PongChannelPath is the channel path for 'pong' operation
    PongChannelPath = "pong"
)

// ChannelsPaths is an array of all channels paths
var ChannelsPaths = []string{
    PingChannelPath,
    PongChannelPath,
}

That would let you check that necessary channels are generated. Would it be enough for you or did you expected something different/had something different in mind ? :)

exactly, thanks for super quick answer!

I am just trying to add it our code base, so if the PR gets merged, I probably will have some time to make a PR, but very hard to promise for me.

No problem ! Should be quick to write, I'll do that today or, more likely, tomorrow :)
