[FEATURE] Maintain line breaks when searching in Logs Explorer

[alex-stiff]

Is your feature request related to a problem?
When constructing a PPL query, it is often useful to split the query onto multiple lines to make it easier to visually parse. However, when searching with the "refresh" button, the newlines in the query search box are stripped.

What solution would you like?
It would be useful if the query new lines/whitespacing was respected, even if the actual search data sent to the Opensearch backend has the newlines removed.

Example
Compare the ease of reading:

index=my-index-* 
| where syslog.host = "srvr123" 
| where not match(syslog.message, 'Admin')
| where not match(syslog.message, 'Host')
| where not match(syslog.message, 'XML')
| where not match(syslog.message, 'iLO ')
| rename host.name as loghost
| rename syslog.host AS host
| rename syslog.tag AS tag
| rename syslog.pri AS priority
| fields @timestamp,loghost,host,tag,priority,message

Vs:

index=my-index-* | where syslog.host = "srvr123" | where not match(syslog.message, 'Admin')| where not atch(syslog.message, 'Host')| where not match(syslog.message, 'XML')| where not match(syslog.message, 'iLO ')| rename ost.name as loghost| rename syslog.host AS host| rename syslog.tag AS tag| rename syslog.pri AS priority| fields @timestamp,loghost,host,tag,priority,message
