stream-clone-test: simplify the case testing phases

There is only two important things in this test:

  - the number of file we send, to show we picked the phase roots.
  - the resulting phases, to show we did not modified them.

The rest are of the number are very fragile and consume a lot of time for little
value when adjusting formats, caches, and protocol.

 Check local clone
 ==================
 
 The logic is close enough of uncompressed.
 This is present here to reuse the testing around file with "special" names.
 
   $ hg clone server local-clone
   updating to branch default
   1088 files updated, 0 files merged, 0 files removed, 0 files unresolved
 
 Check that the clone went well
 
   $ hg verify -R local-clone -q
 
 Check uncompressed
 ==================
 
 Cannot stream clone when server.uncompressed is set to false
 ------------------------------------------------------------
 
 When `server.uncompressed` is disabled, the client should fallback to a bundle
 based clone with a warning.

 Basic clone
 -----------
 
 Check that --stream trigger a stream clone and result in a valid repositoty
 
 We check the associated output for exact bytes on file number as changes in
 these value implies changes in the data transfered and can detect unintended
 changes in the process.

 getbundle requests with stream=1 are uncompressed

 We check that `getbundle` will return a stream bundle when requested.

 --uncompressed is an alias to --stream
 ---------------------------------------
 
 The alias flag should trigger a stream clone too.
 
   $ hg clone --uncompressed -U http://localhost:$HGPORT clone1-uncompressed

   no changes found (stream-legacy !)
 
 Clone with background file closing enabled
 -------------------------------------------
 
 The backgound file closing logic should trigger when configured to do so, and
 the result should be a valid repository.
 
   $ hg --debug --config worker.backgroundclose=true --config worker.backgroundcloseminfilecount=1 clone --stream -U http://localhost:$HGPORT clone-background | grep "background file closing"

   $ hg verify -R clone-background --quiet
 
 Cannot stream clone when there are secret changesets
 ----------------------------------------------------
 
 If secret changeset are present the should not be cloned (by default) and the
 clone falls back to a bundle clone.
 
   $ hg -R server phase --force --secret -r tip
   $ hg clone --stream -U http://localhost:$HGPORT secret-denied

   $ killdaemons.py
 
 Streaming of secrets can be overridden by server config
 -------------------------------------------------------
 
 Secret changeset can still be streamed if the server is configured to do so.
 
   $ cd server
   $ hg serve --config server.uncompressedallowsecret=true -p $HGPORT -d --pid-file=hg.pid
   $ cat hg.pid > $DAEMON_PIDS
   $ cd ..
 
   $ hg clone --stream -U http://localhost:$HGPORT secret-allowed

   searching for changes (stream-legacy !)
   no changes found (stream-legacy !)
 
   $ killdaemons.py
 
 Verify interaction between preferuncompressed and secret presence
 -----------------------------------------------------------------
 
 Secret presence will still make the clone falls back to a normal bundle even if
 the server prefers stream clone.
 
   $ cd server
   $ hg serve --config server.preferuncompressed=true -p $HGPORT -d --pid-file=hg.pid
   $ cat hg.pid > $DAEMON_PIDS

   $ killdaemons.py
 
 Clone not allowed when full bundles disabled and can't serve secrets
 --------------------------------------------------------------------
 
 The clone should fail as no valid option is found.
 
   $ cd server
   $ hg serve --config server.disablefullbundle=true -p $HGPORT -d --pid-file=hg.pid
   $ cat hg.pid > $DAEMON_PIDS

 Local stream clone with secrets involved
 ----------------------------------------
 
 (This is just a test over behavior: if you have access to the repo's files,
 there is no security so it isn't important to prevent a clone here.)

   $ hg -R server phase --draft 'secret()'
 
 Stream clone while repo is changing:
 ------------------------------------
 
 We should send a repository in a valid state, ignoring the ongoing transaction.
 
   $ mkdir changing
   $ cd changing
 
 prepare repo with small and big file to cover both code paths in emitrevlogdata
 (inlined revlog and non-inlined revlogs).

 --------------------------------
 
 The bookmark file should be send over in the stream bundle.
