#### ISSUE TYPE

- Bug Report

#### SUMMARY
In anisble playbook we can specify ‘aliases’ for certain parameters if available
But if we do say a typo in the parameter name then playbooks fails with "Unsupported parameter"
the message “Unsupported parameters..” shows all the parameters that are supported, but these doesn’t include the aliases.
Code:
Say module has the following
```
zone_member_spec = dict(
        pwwn=dict(required=True, type='str', aliases=['device-alias']),
        devtype=dict(type='str', choices=['initiator', 'target', 'both']),
        remove=dict(type='bool', default=False)
    )
```
 The parameter 'pwwn' has alias 'device-alias', but the error shown is 
```
fatal: [m9250i-107]: FAILED! => {"changed": false, "msg": "Unsupported parameters for (nxos_zone_zoneset) module: dxevice-alias found in zone_zoneset_details -> zone -> members. Supported parameters include: devtype, pwwn, remove"}
```
Here I expected  “Supported parameters include: devtype, pwwn/device-alias, remove”
```

''' read the modules parameters and store them globally.
    This function may be needed for certain very dynamic custom modules which
    want to process the parameters that are being handed the module.  Since
    this is so closely tied to the implementation of modules we cannot
    guarantee API stability for it (it may change between versions) however we
    will try not to break it gratuitously.  It is certainly more future-proof
    to call this function and consume its outputs than to implement the logic
    inside it as a copy in your own code.
