Handling of secrets using Evolve

[Lothrandir]

Hi

I suggest adding

var resolvedConnectionString = options.ConnectionString;
foreach (var entry in MapPlaceholders(options.Placeholders, options.PlaceholderPrefix, options.PlaceholderSuffix))
{
    resolvedConnectionString = resolvedConnectionString.Replace(entry.Key, entry.Value);
}
var cnn = CreateConnection(options.Database, resolvedConnectionString);

to the top of EvolveFactory.Build to allow parameters like user and password for connection string to be passed as placeholders. Then the connection string can be stored in an args file but the secrets passed from wherever they are stored. This would make it easier to use in deployment pipelines.

Yep interesting idea, thx
I will add this new feature in a Evolve alpha3 version as soon as possible (by the end of the week hopefully)
I'll let you know
