Describe testing done for PR

1. The command tanzu builder cli compile --match package --version $(make version) --ldflags "-X 'github.com/vmware-tanzu/tanzu-framework/pkg/v1/buildinfo.Version=v0.27.0-dev'" tested with --ldflags having Version info, works fine.
2. The command tanzu builder cli compile --match package ---ldflags "-X 'github.com/vmware-tanzu/tanzu-framework/pkg/v1/buildinfo.Version=v0.27.0-dev'" tested without --version flag, works fine.
3. The new make target build-plugin-local tested: With valid plugin name make build-plugin-local PLUGIN_NAME=package works fine, builds the given plugin. Also tested with empty and in-valid PLUGIN_NAME, it does throw an error saying: The PLUGIN_NAME: '' is not valid or not exists or empty, please provide valid PLUGIN_NAME.

build-plugin-local will compile the plugin and put it in the artifacts directory within the repository.

We should add install-plugin-local that installs the plugin as well. Because as a end user I would like to do some change in the plugin, then I want to build as well as install the plugin to test my change.

Nit:

• git recommends that the commit title (the first line) be 50 characters or less. This is useful because that line is used in many different git outputs (see the first paragraph from https://git-scm.com/docs/git-commit#_discussion)
• as for the text of the commit, it is recommended that it wraps at 72 characters. If not, it makes git log hard to read, among other git output.

A couple of things to clarify

[chandrareddyp]

build-plugin-local will compile the plugin and put it in the artifacts directory within the repository.

We should add install-plugin-local that installs the plugin as well. Because as a end user I would like to do some change in the plugin, then I want to build as well as install the plugin to test my change.

Implementation has updated to add new make target install-plugin-local to build and update given plugin locally.
