Support concurrent activations

[herzog31]

Recently concurrent activations were merged into OpenWhisk. For details, please check

• enable concurrent activation processing apache/openwhisk#2795
• enable use of concurrency action limits via cli apache/openwhisk-cli#383

As far as I understand, the concurrency is expected as part of the limits parameter and shout be treated similar to the memory and timeout parameters. See

serverless-openwhisk/compile/functions/index.js

Line 80 in bba1548

limits: { timeout: params.Timeout * 1000, memory: params.MemorySize },

The scope of this issue is to support the usage of the concurrency parameter.

Thanks for letting us know @herzog31 - we should add this. This is a relatively simple fix - as the concurrency is controlled with the concurrency flag looking at the CLI PR.

Would you like to have a go at submitting the PR?

If you follow the code for setting the other limits, if should be a super-simple PR to open.

@jthomas Yeah, I'll open a PR this week :)
