EF Core Migration Bundles: no way to passthrough custom args to generated efbundle

[bo-bac]

I use IDesignTimeDbContextFactory and custom args in CreateDbContext(string[] args)

Then it is possible to apply update like so
`dotnet ef database update -- --environment TEST

It is expected to do the same with bundles
` .\efbundle.exe -- --environment TEST

Note for triage: repros for me.

PS C:\local\code\AllTogetherNow\SixOh> dotnet ef database update -- --environment TEST
Build started...
Build succeeded.
--environment
TEST

Doh, looks like I forgot to set AllowArgumentSeparator to true in MigrationsBundle.Configure.
