Website request: Create /tables landing page

[eashaw]

Goal:

Add a landing page for the /tables documentation that tells users what osquery tables are and how they are used, highlight commonly used tables, and display a full list of all tables. (When we add the docs navigation bar, there will be no platform-agnostic list of tables on the page.)

We can also create categories (e.g., hardware, software, network, configuration) on the landing page, where we present a curated list of 3-4 tables per category to give users who may not know what kind of information osquery can retrieve a better of idea about what the can do with osquery.

e.g.,
Hardware:

• battery
• cpu_info
• memory
• network_interfaces

Software:

• software
• apps
• services
• running_processes

Configuration:

• configuration_profiles
• mdm
• managed_policies
• startup_items
