Metaflow

This is a patch release addressing a behavior of the environment escape mechanism.

Bug Fixes
* Previously, if the environment escape mechanism provided a package, a failure would occur if that package was also present in the inner environment. This is now changed and, in that case, the package present is used and the environment escape mechanism is not used.

This is a minor release which primarily adds the ability to do runtime tagging.

Features
* Adds the ability to mutate a run's tags during or after a run. A CLI tool is provided (`tag`) as well as methods in the client `add_tags`, `replace_tags` and `remove_tags`. If using the Metaflow Metadata service, a version greater than 2.3.0 is required to use this feature.

The Metaflow 2.6.3 release is a minor release

Bug Fixes
* Fix instance metadata calls for IMDSV2 in https://github.com/Netflix/metaflow/pull/1053

The Metaflow 2.6.2 release is a minor release

Features

* Support setting default secrets for `kubernetes` ([1048](https://github.com/Netflix/metaflow/pull/1048) ). Metaflow allows you mount secrets in Kubernetes containers created by tasks. Now you can specify a set of secrets to be mounted by default via `METAFLOW_KUBERNETES_SECRETS` configuration option, in addition to existing `kubernetes(secrets="...")` API.

Fixes

* When using ` --run-id-file`, the file is now written _prior_ to execution when resuming a flow ([1051](https://github.com/Netflix/metaflow/pull/1051)). That matches how `run` command behaves already.

<a name="v2.6.1_bugs"></a> Bug fixes
* Fixed card rendering for tables with some NaN values (https://github.com/Netflix/metaflow/issues/1023) in https://github.com/Netflix/metaflow/pull/1025

The Metaflow 2.6.0 release is a minor release and introduces Metaflow's integration with [Kubernetes](https://docs.metaflow.org/metaflow/scaling-out-and-up/effortless-scaling-with-kubernetes) and [Argo Workflows](https://docs.metaflow.org/going-to-production-with-metaflow/scheduling-metaflow-flows/scheduling-with-argo-workflows)
- [Features](2.6.0_features)
- Add capability to launch Metaflow tasks on Kubernetes and schedule Metaflow flows with Argo Workflows.
- Expose `tags` in `current` object.

<a name="v2.6.0_features"></a> Features
Add capability to launch Metaflow tasks on Kubernetes and schedule Metaflow flows with Argo Workflows.
This release enables brand new capabilities for [Metaflow on top of Kubernetes](https://outerbounds.com/blog/human-centric-data-science-on-kubernetes-with-metaflow/). You can now [`run --with kubernetes`](https://docs.metaflow.org/metaflow/scaling-out-and-up/effortless-scaling-with-kubernetes) all or parts of any Metaflow flow on top of _any_ Kubernetes cluster from your workstation. To execute your flow asynchronously, you can deploy the flow to Argo Workflows (a Kubernetes-native workflow scheduler) with a single command - [`argo-workflows create`](https://docs.metaflow.org/going-to-production-with-metaflow/scheduling-metaflow-flows/scheduling-with-argo-workflows).

To get started, take a look at the [deployment guide for Kubernetes](http://lin/). Your feedback and feature requests are highly appreciated! - please reach out to us at slack.outerbounds.co
