ffmpeg makes a new request for DELETE regardless of http_persistent

[ffmpeguser68068]

Summary of the bug:

ffmpeg creates a new tcp/http connection for deleting segments (DELETE request), regardless of http_persistent

if http_persistent is set to one, create a separate persistent connection (for DELETE requests), the same way as PUT request connections (one for media segments, and one for the playlist)

How to reproduce:

ffmpeg -re \
	-i testfile.flac \
	-vn -c:a libopus \
	-f dash \
	-seg_duration 4 -window_size 4 -use_template 1 -use_timeline 1 -extra_window_size 0 \
	-method PUT -http_persistent 1 \
	-init_seg_name "streaminit-\$RepresentationID\$.\$ext\$" \
	-media_seg_name "media-\$RepresentationID\$-\$Number%08d\$.\$ext\$" \
	'http://127.0.0.1/webdav/stream.mpd'
