split Azure packages into dedicated nuget packages

[adamsitnik]

This PR contains following changes::

• split HealthChecks.AzureStorage into Storage, Files and Queues packages
• remove HealthChecks.AzureStorage
• move Azure Tables health check from HealthChecks.CosmosDb to dedicated package
• move Azure Event Hubs health check from HealthChecks.AzureServiceBus to dedicated package
• enforce Azure health checks: How to steer the users towards best practices #2040
• add missing README.md

What is not included in this PR (I'll send a separate PR after this gets merged):

• sign new assemblies
• update to 8.0 microsoft extensions

fixes #2040
fixes #1371 (health check reuse registered clients rather than creating new onesS)
fixes #1567 (client instance is created lazily when needed for the first time)
fixes #665 (two health checks were using the same name)

Hi @adamsitnik

The idea is mantain the AzureStorage package with 3 references to Tables, Queues and Shares? Why not deprecated current Storage and move the IHealthCheckBuilder extensiosn to each package?
