Add trackAllCaptures for Back References in Url Rewrite

[BrennanConroy]

e.g.

<condtions trackAllCaptures="true">
  <add input="{QUERY_STRING}" pattern="id=(20)" />
  <add input="{HTTP_HOST}" pattern="(.*)" />
</conditions>
<action type="Redirect" url="https://{C:2}" />

Remember, trackAllCaptures is part of the back reference feature

BasicMiddleware/src/Microsoft.AspNetCore.Rewrite/Internal/IISUrlRewrite/UrlRewriteFileParser.cs

Line 133 in 89a6f45

builder.AddUrlConditions(grouping, trackingAllCaptures);

[BrennanConroy]

The correct name is trackAllCaptures not trackingAllCaptures

BasicMiddleware/src/Microsoft.AspNetCore.Rewrite/Internal/IISUrlRewrite/RewriteTags.cs

Line 24 in 89a6f45

public const string TrackingAllCaptures = "trackingAllCaptures";

BackReference uses RegularExpressions.GroupCollection which doesn't have additive operators, so we'll have to change the structure used to contain the back references.

@mikaelm12 Let's fix the enum name in 1.1. And investigate the back referencing issue. If the potential fix for that is not breaking, we can do it in 1.2 instead.

Okay. I changed the enum in #166
This bug should be moved to 1.2 though
