Using HTTP(S)_PROXY in odo

User Story

As an odo user, my working environment is restricted, and all requests need to go via a proxy I want to be able to configure odo to use a proxy So that I can use odo.

Acceptance Criteria

• odo should use system proxy settings (HTTP_PROXY and HTTPS_PROXY env variables) for all requests

## Notes

• requests done using client-go should be already correctly routed via the proxy
• devfile registry library is currently most likely not supporting proxy
• all requests done by odo itself should go via proxy as well (including telemetry)

devfile registry library is currently most likely not supporting proxy

support or HTTP_PROXY was merged in devfile/library (devfile/api#897)

[valaparthvi]

• update the devfile library
• update all the HTTP client calls.(reference: proxy support for registry devfile/registry-support#133)
• add a note in the docs(?) to ensure we use this in future implementations.
• test, even if manual

Just wanted to check to see if there is a timeline for when this request makes it into the binary.

Thanks in advance.

devfile/registry-support#133 fixes the problem in Registry library and #6396 includes this PR.

This fixes the problem for calls to Registry.

I executed tests with a Squid proxy and iptables blocking all other outbound traffic except to proxy, all tests pass.
