Add an "AcceptEula" API to containers that use environment variables to signal EULA acceptance.

Some containers have a EULA acceptance process where you add an environment variable. Rather than adding these environment variables automatically we should provide a mechanism for developers to explicitly opt into this. This means that their first run of a particular resource will likely fail, they'll get an error and then apply another method. Here is an example of how it could work:

Container resource example

builder.AddSqlServer("sql")
       .WithAcceptEula(true);

Related resource example

builder.AddRedis("redis")
       .WithRedisInsights(c => c.WithAcceptEula(true));

Do we know that it's the first run that fails? Today we auto accept the eula for Seq and SqlServer. These need to be undone and it has to be opted into by customers.

[mitchdenny]

I think in the case on SQL it means every run where that environment variable isn't present.

Do you think we should apply this one in related PR? or can be a follow up?

I think we should not auto accept the Eula in the redis insight PR
