Spec: implement an option to limit length of values of attributes and metric values

[rauno56]

Ref: open-telemetry/opentelemetry-specification#1130

[CptSchnitz]

will the length limit will be configurable from the code, or only from env? (from looking at the java implementation it looked only from env, but I'm not that good with java)

Hey,

I would like to contribute to this feature if no other working on the same.

@rauno56 can you assign this to me.

[banothurameshnaik]

Hey all,

I implemented the option to limit length of attribute values (not yet for metrics).

Please have a look into #2418

[rauno56]

OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT is now covered! Thanks, @banothurameshnaik!
Reopening it because the spec has two other attributes:

• OTEL_ATTRIBUTE_VALUE_LENGTH_LIMIT and
• OTEL_ATTRIBUTE_COUNT_LIMIT.

[banothurameshnaik]

@rauno56
I will continue working on implementing these two attributes also.
Will raise another PR.

Hi,
I made an PR with OTEL_ATTRIBUTE_VALUE_LENGTH_LIMIT and OTEL_ATTRIBUTE_COUNT_LIMIT limits.
Please have a look.
