Fix for longer UserAgent suffix

[ealsur]

Pull Request Template

Description

This PR applies a refactor on the UserAgentContainer, creating a child class Cosmos.UserAgentContainer that has a different base user agent. The new base user agent uses EnvironmentInformation and generates a format of:

{OS}/{Process Architecture} {SDK Version}/{Direct pkg Version}-{Framework} {ClientId} {UserSuffix}

For example:

Microsoft Windows 10.0.18362 /X64 3.1.1/3.1.4-.NET Core 4.6.27617.04 03445 mycustomsuffix

The information is read from the RuntimeEnvironment NET Standard 2.0 https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.runtimeenvironment?view=netstandard-2.0

Windows/10.0.17763 cosmos-netstandard-sdk/3.1.4 3.1.1-.NET Core 4.6.26614.01 X64 637014000798739244

Can it be abstracted to the scope we need. I.e. may-be

W/X64-WACosmos/3.1.... -.NET Core 4.6.26614.01

Thoughts?

The problem is that the initial part comes as part of the UserAgentContainer defined in Direct package, which is used down the stack.

The alternative would be to redefine the class?

@kirankumarkolli I ended up refactoring this PR. The new introduced logic was too complex, so I ended up simplifying this by creating our own UserAgentContainer that inherit from UserAgentContainer from Direct but defines our own base user agent string, with the information we wanted (Package versions, etc)

[kirankumarkolli]

Can you please share new user-agent string?

@kirankumarkolli it's in the PR description, I updated the description when I refactored
