Change couchbase-cli to use commas not semicolons for server-add-services

When adding a server to a cluster you have the option to choose which services are added, this is delimited with a semicolon, can this be changed to use a comma instead ?

Some places in the documentation have

couchbase-cli server-add -c 10.3.2.204:8091 -u Administrator -p password --server-add=10.3.4.246:8091 --server-add-username=Administrator --server-add-password=password --server-add-services="data;index;query"

While others have

Services that run on the server. To specify multiple services, separate the service with a semi-colon. For example, --services=data;index.

This is going to cause problems for customers as it is an easy mistake to miss off the quotes and I do not believe this should be solved with documentation alone.

Running this command will execute but the index service will be missing. It's also not possible to add the service to the node afterwards.

couchbase-cli server-add -c 10.3.2.204:8091 -u Administrator -p password --server-add=10.3.4.246:8091 --server-add-username=Administrator --server-add-password=password --server-add-services=data;index

The issue is the bash shell will interpret the semicolon as the end of the command line and it will then interpret index as a new command to execute independently.
