SOLR-17740: V2 API: fix raw file uploads missing 1st byte (#3322)
SolrRequestParsers can consume one byte of the underlying stream, but V2 was
ignoring the SolrQueryRequest content stream. Fix is to detect HTTP body in a
more standards-compliant way; don't read a byte to see.
> JAX-RS V2 API requests with payloads can skip first byte

> The new V2 API (JAX-RS, Jersey) has its own stack of code between Solr's
> V2HttpCall and the handler, that which doesn't know about the
> SolrQueryRequest. Â Specifically
> {{org.apache.solr.api.V2HttpCall#handleAdmin}} doesn't use {{solrReq}} as it
> passes on to {{{}invokeJerseyRequest{}}}. But the payload of the request has
> been somewhat parsed already into the ContentStream on SolrQueryRequest, and
> this can sometimes require reading the first byte – see
> {{{}org.apache.solr.servlet.SolrRequestParsers.RawRequestParser#parseParamsAndFillStreams{}}}.
> Consequently V2 requests like FileStore uploadFile can be impacted depending
> on the details of the headers present.
> In practice, Jetty HttpClient intermittently was triggering affected and
> unaffected requests when executing the following test:
> {{./gradlew :solr:core:test --tests
> "org.apache.solr.cli.PackageToolTest.testPackageTool"
> -Ptests.seed=B8415E6AAC736FCD}}
