Debounce credential prompts and check profile locks in more places

[traeok]

Proposed changes

• Adds a 30 second timeout to waitForUnlock to prevent deadlocks when using the function (safety mechanism)
• "Debounces" credential prompts from parallel requests to a mainframe system by only showing one credential prompt, until the user answers that prompt.
  • Behavior remains unchanged: If the user selects "Cancel" or closes the dialog, the profile remains locked. The user can update their profile through the tree views through the "Manage Profile" to unlock the profile in the filesystem.
  • Resolves an issue where the user was spammed with multiple credential prompts when using a virtual workspace with a profile w/ invalid credentials.
• Eliminated cached profile use in filesystems: All filesystem requests will get the latest profile object to prevent invalid, cached credentials from being used.
  • The issue still exists in tree views for credential desync in the quick picks. I have filed issue # to track/resolve this in the future.

Release Notes

Milestone: 3.1.2

Changelog:

• Fixed issue where users were prompted several times when using a profile with invalid credentials in a VS Code workspace. Now, the user is only prompted once per profile, allowing the user to enter in new credentials.
