Service Level N1QL request timeout syntax is incorrect

The command used to modify the Service Level request timeout for N1QL queries is specified in the docs as follows:

curl http://hostname:8093/admin/settings -d '{"timeout":"30m"}' -u user:pword

This command is not valid and throws the error Incorrect value 30m for setting: timeout:

$ curl http://localhost:8093/admin/settings -d '{"timeout":"30m"}' -u Administrator:password

{"caller":"set_params:116","code":2032,"key":"admin.setting_type_error","message":"Incorrect value 30m for setting: timeout"}

The correct syntax accepts a number in nanoseconds without any units and is as follows:

curl http://hostname:8093/admin/settings -d '{"timeout":30}' -u user:pword

The above command sets the timeout to 30 nanoseconds.

We should change to docs to reflect this. We should also remove the statement mentioning that the fields are mandatory:

Its format includes an amount and a mandatory unit. Valid units are:

ns (nanoseconds)

us (microseconds)

ms (milliseconds)

s (seconds)

m (minutes)

h (hours)

Ex: "10ms" (10 milliseconds) and "0.5s" (half a second).

Alternatively, we could change the Query Settings REST API code to accept the units as mentioned in the docs.
