Imperative `postInstall` hook stops other plugins from being installed

[zFernand0]

Describe the bug

Given that a user runs zowe plugins install plugin-A plugin-B
When the plugin-A throws an error in its AbstractPluginLifeCycle.postInstall() function
Then the plugin-B is not installed

Expected and actual results

Expected the error to be recorded using the PMF's recordIssue functionality.
Also expected to be able to install plugin-B

Describe your environment

• Zowe CLI version installed (run command zowe --version): 8.35.3
• Installed plug-ins and their version numbers (run command zowe plugins list --short): None
• Node.js and NPM versions installed (run node --version, npm --version): any version of NodeJS and NPM
• Environment variables in use: N/A
• Operating system and version: MacOS
• Shell/terminal (bash, cmd, powershell, etc...): zsh
• Daemon mode enabled or disabled: disabled
• For more information, see Gathering information to troubleshoot Zowe CLI

Consideration for the fix : we still want any plugin install command with a failing postInstall hook to result in a non zero exit code. We just don't want the install process to immediately stop
