Azure-cli: query operator with JMESPath doesn't handle a 'dash' (-) properly

[cicorias]

If a tag on a resource has a name that includes a - the query fails incorrectly.

To Reproduce

1. Assign a tag of CREATED-BY to a resource group in Azure with a value of 'foobar'
2. Run the Query
   az group list -o tsv --query "[?tags.CREATED-BY == 'foobar']"

Expected behavior
Normally the results will show the item.

Actual result
The error shows as

az group list: error: argument --query: invalid jmespath_type value: "[?tags.CREATED-BY == 'foobar']"

If you run a similar query on http://jmespath.org/ as below, it works fine

locations[?state == 'WA' && foo-bar == 'foobar'].name | sort(@)

Using data of:

{
  "locations": [
    {"name": "Seattssle", "state": "WA", "foo-bar": "foobar"},
    {"name": "New York", "state": "NY"},
    {"name": "Bellevue", "state": "WA"},
    {"name": "Olympia", "state": "WA"}
  ]
}

Environment summary
This is verified to fail in the Azure Cloud Shell.

Sorry for running into such troubles, but Jemspath requires the property be a valid identifier unless you wrap them with quotes . Because of the -, CREATED-BY is not a right id, so please wrap it.

(env) D:\sdk\azure-cli>az group list -o tsv --query "[?tags.\"CREATED-BY\" == 'yugangw']"
/subscriptions/0b1f6471-1bf0-4dda-aec3-cb9272f09590/resourceGroups/yg4  westus  None    yg4

@tjprescott, @williexu, I am closing this, but if we receive more such confusions, we need to document of how to use jmespath.

JFYI, the grammar syntax is here
