[CLIENT-4702] Convert docstring code examples to doctest format and validate them

[juliannguyen4]

Extra Changes

• Replaced the code example for client.udf_put(), client.udf_list(), and client.udf_remove() with a higher level code example for the "User Defined Functions" section. The latter is verified to run without errors using doctest and demonstrates the outcomes of those API calls.
• Add ability to copy code examples while also stripping any characters that aren't valid Python syntax
• Remove bad code example for HyperLogLog class. Normally, HyperLogLog bins are created using operations or expressions.

Known issues introduced here

• The testsetup code block isn't visible by default, so we have to have a duplicate codeblock to show that code. This introduces some technical debt, and having the testsetup code visible is a missing feature in Sphinx

Trade-offs

• Code examples are harder to run because the Python REPL gives a syntax error when it encounters >>>. As a workaround, developers have to use IPython REPL with their specific desired version of Python to copy and run the code examples

Manual testing

• https://aerospike-python-client--1047.org.readthedocs.build/en/1047/aerospike.html
• https://aerospike-python-client--1047.org.readthedocs.build/en/1047/aerospike_helpers.batch.html
• https://aerospike-python-client--1047.org.readthedocs.build/en/1047/aerospike_helpers.expressions.html
  • HLL boilerplate code is rendered properly
• https://aerospike-python-client--1047.org.readthedocs.build/en/1047/aerospike_helpers.operations.html#module-aerospike_helpers.operations.expression_operations

TODO

• aerospike needs to be compiled before running doctest
• Copying doctest formatted code into Python REPL causes syntax errors related to >>> Moved to a different format from doctest
• client.info_all() output format is kinda weird...

Out of scope

• Doctest teardown
