[Feature Request] Allow to set parameters for pipelines runs

[alxy]

Is your feature request related to a problem? Please describe.
It would be nice if I could run pipelines programmatically (from Azure CLI) and set parameteres for the run, as I am also able to when using the ADO pipeline interface. The suggested interface would look like this:

az pipelines run --id 123 --parameters "{'name': 'value'}"

As parameters accept complex typed values I would suggest passing a JSON string.

Describe the solution you'd like
The most recent REST API for pipelines runs allows to specify templateParameters. Thus, it shoud be possible to implement this feature using this endpoint.

Additional context
This feature could come in handy in larger projects to orchestrate automation pipelines, as I am able to queue this pipelines in a particular order with a specific set of parameters and variables.

This sounds like a dupe of #972

@alxy for our better understanding can you please share if you are able to use variables or not in the existing command?

or is the ask for something else ?

@gauravsaralMs Azure pipelines support variables and parameters. These are two different concepts (I think parameters are evaluated at queue time, while variables can even be set/changed during runtime of a pipeline), and my request is for the later :)
