Add ability to hide all time tracking information

When using Jira Server, plugins are able to hide all time tracking information from issues, etc. But this isn't possible in Cloud.

It is not possible to hide time tracking and estimation information in Jira Cloud in the following places:

• “History” issue tab panel

• “All” issue tab panel

• “Time tracking”, “Original estimate”, “Remaining estimate” fields in the right panel of issue view

• “Original estimate”, “Remaining estimate” columns in issue search

Please add the ability to hide these values the same as with Server through an API.
