SchemaRegistryClient fails to instantiate due to httpx changes

See original GitHub issue

Describe the bug

Failure to instantiate client:

File "/usr/local/lib/python3.7/site-packages/schema_registry/client/client.py", line 45, in SchemaRegistryClient
--
  | pool_limits: httpx.PoolLimits = httpx._config.DEFAULT_POOL_LIMITS,
  | AttributeError: module 'httpx._config' has no attribute 'DEFAULT_POOL_LIMITS'

It’s most likely caused by changes in httpx library (particular version is not pinned in schema registry client deps)

https://github.com/encode/httpx/commit/f67e925f72166ac89c4ff430540173b5910ec315#diff-11c528b34fa1b897a86107c0a46b252f

Explicit downgrade httpx to 0.13.3 resolves this issue.

To Reproduce Steps to reproduce the behavior:

Install python schema registry client with latest httpx lib and try to create client.

Expected behavior Client is created ok.

@mgorsk1 As Marcos points out, version 1.4.2 should fix your issue (i.e. https://github.com/marcosschroh/python-schema-registry-client/blob/master/schema_registry/client/client.py#L45 no longer references httpx._config.DEFAULT_POOL_LIMITS).

@miandreu The full traceback of your error and the output of python -mpip list | grep "python-schema-registry-client\|httpx" might help narrow down where exactly you’re seeing this issue.
