perf: move pods installation from init to ios-specific commands

[TMisiukiewicz]

Summary:

Currently Pods are installed during init command, what makes project setup much longer than it supposed to be. This change makes pods installation optional during the init command by displaying the prompt, and moves the installation process to the run-ios and build-ios commands. Pods are automatically installed when running ios-specific commands and:

• they were not installed before
• a new dependency/devDependency was introduced in package.json
• new flag --force-pods was used, which forces to install pods (might be helpful when there are any errors related to pods)

Additionally, new flag --install-pods was introduced to init command, to avoid displaying prompt. If set to true, pods will install, false will skip the installation, and when not used, prompt will be displayed.

To install pods during *-ios command, it compares md5 hashes of native dependencies names and its versions. To achieve this, I added one new field to dependency config: version which holds the version of the library from package.json/podspec file.

Demo

1. init with prompt

2. init with --install-pods false - skip prompt and pods installation

3. run-ios for the first time (cut the video because it takes too long 😄, app runs after installation)

Test Plan:

1. Follow the contributing instructions
2. Init new project - it should display prompt about pods installation
3. Press y to confirm - pods should be installed
4. Init new project once again - it should display prompt
5. Press 'n' - pods installation should be skipped
6. Init new project with --install-pods flag - pods should be installed automatically
7. Init new project with --install-pods false - prompt & pods installation should be skipped
8. Run run-ios command and verify pods are installed before building the app
9. Run run-ios again and verify app is built without installing pods
10. Install any random dependency, e.g. @react-navigation/native
11. Run run-ios again and verify pods are installed before building the app
12. Run run-ios again and verify app is built without installing pods
13. Run run-ios --force-pods and verify pods are installed before building the app
