@gbbafna - Users who upgrade to this release will have the default value updated without them noticing. Do you think it makes sense to document this as a part of release highlights?

Description
The default
segrep.pressure.time.limitis 5 mins , while defaultsegrep.pressure.checkpoint.limitis just 4 which only allows for 40 sec lag given the refresh interval of 10 secs . Though the default refresh interval is 1sec, for remote backed clusters, we advice >10 sec due to prohibitive costs and high resource consumption of segment upload every sec. This PR increasessegrep.pressure.checkpoint.limitto 10 so that both checkpoint limit and time limit equates to same 300 sec and we don't give unnecessary rejections to the user .This relaxation is due to the fact that we don't have multipart download or block level fetches in download part, hence the observed lag on clusters are on a higher side (100s of seconds) during force merges .
