sap_ha_pacemaker_cluster: Corosync Totem platform dictionary

[marcelmamula]

Description:

• Enhanced corosync totem variables for each platform based on Cloud providers
• Switch to dictionary, similar to stonith dictionary
• Added documentation links

Important:

• Some dictionaries are simplified because there are no differences either between OS or HANA/NWAS - Similar to stonith dictionaries.

Example for AWS, which includes differences for both OS and host type:

# Default corosync options - Platform specific
# These options combined with __sap_ha_pacemaker_cluster_corosync_totem_default (Same options are overwritten).
