* Prohibit usage of retired names in semantic conventions
This change adds a prohibition clause that requires that no old
metric or attribute name is used for a new attribute.
This is important to ensure reversibility of schema transformation
(converting from a new version to an old version of schema).
Without this restriction the following is possible:
Schema version 1. Attribute A exists.
Schema version 2. Attribute A is renamed to B. Appropriate schema file is created.
Schema version 3. Attribute A is introduced (a completely different new attribute).
Now attempting to go from Version 3 to version 1 is impossible since it requires
renaming B to A (for the change in version 2), but a different attribute A already exists.

A 'process.runtime' namespace is currently defined in the resource
semantic conventions. The metric semantic conventions suggest that
runtime metrics use a 'runtime' namespace. Since the runtime metrics
are directly related to the runtime resources, they ought to share a
common namespace.

* Have consistent formatting for semantic convention enums
Currently, semantic convention enum values are not consistent.
For example, os.type values are all capitals whereas
cloud.infrastructure_service values are underscored lowercase.
This change improves the inconsistencies.
We also expect language implementations to autogenerate code
from enum values. Each language has their own conventions for
constant variable identifiers and we expect the consistent
formatting is going to help the language implementors.
Fixes#1519.
