Allow to specify the kubernetes context

[mool]

It would be nice to add support for the --context argument when holmes is executing the kubectl command. This will allow to run holmes without having to change context

We should be able to add something.

It connects well with work we're doing on tool configuration right now (specifically how do you configure tools that require parameters or credentials to work, like pulling data from Grafana cloud or Elasticsearch?)

Would you be open to a short video chat so I can better understand your requirements and verify the solution works?
