Revert "XSI-1706/CP-51295: limit open TCP connections to 250 and incr…

…ease socket backlog" This reverts commit af7b9c4. We found that the lower limits are too low for large pools and reverting this. We understand that this risks running out of file descriptors, which was the motivation to lower the limits and to introduce rate limits. The problem does not exist in XS8 and we hope to manage this problem until the end of support of this release. Signed-off-by: Christian Lindig <[email protected]>
