Avoid repeatedly invoking pip show in Python lang host (#7831) 
* Avoid repeatedly invoking `pip show` in Python lang host

The Python language host invokes `pip show` for each Pulumi package in a
project at startup. But `pip show` is quite slow in large projects: it
takes 2+ seconds per invocation in a project at @MaterializeInc.

`pip show` is invoked to compute the installed location of each plugin
package. But it turns out `pip list` takes a `-v` flag that can supply
this information in one shot, avoiding the need to ever invoke `pip
show`.

This patch shaves about 20s off our boot time for `pulumi up`.

(There's probably a separate bug in Pip that causes `pip show` to be so
slow, because `pip list` is an order of magnitude faster and does a lot
more work, but I didn't bother tracking that down.)

* Test and fix issue with parsing non-JSON trailer returned by pip

* Fix issues found by Go lint

* CHANGELOG entry

Improvements

  • [auto/dotnet] - Add support for --exact and --server with pulumi plugin install via Automation API. BREAKING NOTE: If you are subclassing Workspace your InstallPluginAsync implementation will need to be updated to reflect the new PluginInstallOptions parameter. #7762

  • [codegen/go] - Add helper function forms $fnOutput that accept Inputs, return an Output, and wrap the underlying $fn call. This change addreses #5758 for Go, making it easier to compose functions/datasources with Pulumi resources. #7784

  • [sdk/python] - Speed up pulumi up on Python projects by optimizing pip invocations #7819

  • [sdk/dotnet] - Support for calling methods. #7582

Bug Fixes

  • [cli] - Avoid missing go.sum entry for module for new Go projects. #7808

  • [codegen/schema] - Allow hyphen in schema path reference. #7824
