Feature Description
support
UPSERT REPLACE as an alias to UPDATE, helps to differentiate put and patch methods with the same signatures

Example(s)

for the following DML operation:

UPSERT INTO google.compute.firewalls
SET field1 = 'value1'
WHERE project = 'my-project'
AND firewall = 'my-firewall'

would use this resource definition...

    firewalls:
      id: google.compute.firewalls
      name: firewalls
      title: Firewalls
      methods:
...
        update:
          operation:
            $ref: '#/paths/~1projects~1{project}~1global~1firewalls~1{firewall}/put'
          response:
            mediaType: application/json
            openAPIDocKey: '200'
        patch:
          operation:
            $ref: '#/paths/~1projects~1{project}~1global~1firewalls~1{firewall}/patch'
          response:
            mediaType: application/json
            openAPIDocKey: '200'
      sqlVerbs:
...
        upsert:
          - $ref: '#/components/x-stackQL-resources/firewalls/methods/update'
        update:
          - $ref: '#/components/x-stackQL-resources/firewalls/methods/patch'
...

to access the upsert route, treated the same as and update but routed to the proper operation in the path
