Move /docs content to component docs folders

[NicolasFussberger]

• Introduce a docs folder for component launch_manger and subcomponent lifecyle_client
• The uxf diagrams are also stored as svg so they render in html. The conversion btw. uxf and plantuml is done in a separate PR
• Move the existing content from /docs to launch_mangager/docs and lifecycle_client/docs
• For the feature documentation, introduce the doc templates from the score module template

Closes: #230

Out of Scope of this PR:

• Moving the feature docs from central score repo to the lifecycle repo (Move feature documentation from central score repo to lifecycle repo #250)
• Introducing the component templates for launch manager component (Align Launch Manager component docs folder with docs templates #249)
