[SparkR][Minor] Add installation message for remote master mode and improve
other messages
## What changes were proposed in this pull request?
This PR tries to give informative message to users when they connect to a
remote master but don't have Spark package in their local machine.
For now, automatic installation will only happen if they start SparkR in R
console (rather than from sparkr-shell) and connect to local master. In the
remote master mode, local Spark package is still needed, but different from
local mode, we will not trigger the install.spark function because the versions
have to match those on the cluster, which involves more user input. Instead, we
provide detailed message that may help the users.
Some of the previous messages have also been slightly changed.
## How was this patch tested?
Manual test.
