Added ask install and ask uninstall commands

[azaan-sherani]

Description of changes:

Added two new commands: ask install --component-name - installs the specified skill component in the alexa skill ask uninstall --component-name - removes the specified skill component from the alexa skill, if it is installed.

These changes are in beta and will require testing and additions before merging it to develop in the future.

Unit tests are missing. At a minimum we should have unit tests for the two new commands in /test/unit/commands/install/index-test.ts and test/unit/commands/uninstall/index-test.ts
