Dev 4 community detection is deterministic

[thibaultprouteau]

Description

• Number of threads is set to 1 in graph-embeddings
• Community detection with Louvain has no randomness with 1 thread and without "none randomized" parallelization strategy.

Fixes #4

• By default number of threads is set to -1, all available threads
• Warning log message is clashing parameters are given for community detection (1 thread and parallelization != "none randomized")
• Added option for passing alternative parallelization strategies from networkit.PLM
• Updated docstrings
• Compiled documentation to reflect changes

Please delete options that are not relevant.

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Run on cora without setting then_jobs parameter of SINr 10 times -> different number of communities
• Run on cora without setting then_jobs parameter of SINr but setting networkit.setNumberOfThreads(1) -> same of communities

Can you please review the changes made to sinr/graph-embeddings.py and tell me if they can be merged to dev ?

Thanks ! 😌
