Query Analytics can't handle colon character (`:`) in service names

User Impact: User cannot See QAN data for specific service
STR:

1. Add service with the name like "my-service:service1"
2. Open QAN
3. Select Service name "my-service:service1"

Expected result: There is no any data for this service

Actual result: There is data for selected service

Original report: When using service names with colon (like on ARN format), QAN filter breaks.

For example, for this service name: instance-name:region:account

Instead of passing variables like this:

?var-service_name=instance-name%3Aregion%3Aaccount

It goes like this:

?var-service_name=instance-name&var-service_name=instance-name&var-service_name=instance-name

The curious thing is that every other dashboard works fine.
