swagger-cli v2.2.2 loses support for RHEL 5

[pancakeslp]

Probably more as an FYI than an issue that will get fixed (as RHEL 5 has been out production support since 2017 ish)

On all my RHEL/OEL/Centos 5 boxes when using v2.2.2 I get the below error

SwaggerParser.prototype.parse = async function (path, api, options, callback) {
                                      ^^^^^^^^

SyntaxError: Unexpected token function

    at Object.validate (/root/code/swagger-api/myoffers/node_modules/swagger-cli/lib/validate.js:22:23)

If I downgrade to version 2.2.1 it works again for me on all RHEL/OEL/Centos 5 boxes I've tested.
Might also be worth noting that my Centos 7 boxes happily accept v2.2.2

I'm not familiar with RHEL 5, but I suspect that it's using an old version of Node. Only Node 8 and newer are supported anymore. Here's the LTS schedule:
