[Improvement]: Add local repository support to the bal tool

[Thevakumar-Luheerathan]

Description

Publish a tool to the local repository
bal push --repository=local

• Copies the bala to the local repo locations and extract.
• Keeps a mapping between tool-Id and org-package name to retrieve them easily with pulling

Use a tool from the local repository

bal tool pull <tool-id>:<version> --repository local

• Adds the tool entry to the bal-tools.toml

[[tool]]
id = openapi
org = ballerina
name = tool-openapi
version = 1.0.1
repository = local
active = true

• This makes the tool available to the user locally and sets it as the active version.

Switch to another version of a tool in the local repository
bal tool use <tool-id>:<version> --repository local

Remove the usage of the tool from the local repository

• Option 1: Execute the bal tool use command to switch to the required version

    `bal tool use <tool-id>:<version>`
  

• Option 2: Remove command removes the entry from bal-tools.toml

    `bal tool remove <tool-id>:<version> --repository local`
