Updated metadata envoy route name

[VaniHaripriya]

The issue resolved by this Pull Request:

Resolves RHOAIENG-5348

Description of your changes:

1. Updated the metadata envoy route name to avoid the issue with creation of pipeline server when the project name is longer than 31 chars.
2. This is the route name before the change - https://ds-pipeline-metadata-envoy-dspa-MYPROJECT.apps.clustername.domain.com/ , when the project name is longer than 31 chars pipeline server fails to create. Updated the route to this format - https://ds-pipeline-md-myproject.apps.clustername.domain.com/ which allows the project name to have more chars.

Testing instructions

Deploy DSPO and create a DSPA instance. The metadata envoy route should be as shown in the below format-
https://ds-pipeline-md-myproject.apps.clustername.domain.com/
