Resolve "Move Analytics out of "More" in top navbar"

What does this MR do?

This MR merges the instance statistics and analytics sidebar items. It also removes the 2 items from the More navbar dropdown and places them into an analytics shortcut option on the navbar.

A simple sounding change, but a lot to consider as this differs between CE and EE;

• CE
  • Rename the Instance Statistics to Analytics for consistency.
  • Display nav link if user has access to instance statistics features
  • Display all available CE features in sidebar
• EE
  • Display the analytics nav link IF
    • User has access to instance statistics features OR
    • Any EE specific analytics features are enabled
  • Display sidebar items based on availability and access to features
    • Display links to enabled EE specific analytics features for all users
    • Display links to instance statistics features if a user has access to them
